Those Who Swift - Issue 266

Wed, 13 May 2026 20:01:18 GMT

Weekly note ✏️

Apple recently shared a list of authors and content creators who are shaping and supporting the iOS community. 👏

From meetup organizers to developers publishing valuable tutorials, tips, and deep dives, this recognition highlights something important.

First, it shows that platform owners fully understand one thing: the ecosystem cannot exist without the people actually building apps and sharing knowledge outside official events like WWDC or Meet with Apple sessions. Learning never stops at documentation. Development moves too fast for that. New frameworks, APIs, architectural patterns, and tools appear constantly, and staying up to date means following many different voices and perspectives. In a way, Apple has created its own watchlist of creators worth paying attention to.

Second, this kind of recognition is genuinely inspiring for authors themselves. More visibility means more readers, more feedback, and more motivation to continue. Consistently creating educational content is a skill polished over years. It takes time, energy, research, editing, and persistence. And knowing that your article, video, or podcast helped someone solve a problem or understand a difficult concept is often what keeps creators going.

Because even the most experienced developers can still pause at subtle details, especially in areas like testing architecture or dependency isolation. That’s why this week we’re sharing a note about Stubs and Mocks.

What learning resource or creator has influenced your development journey the most?

Cut Your Swift Compile Times with Xcode 26

Xcode 26's compilation cache reuses outputs like object files and module artifacts when inputs don't change.

Bitrise was first to support it and saw 19-55% faster builds in testing. The Bitrise team walks through setup and what to expect as it matures.

Accelerate Framework In Swift - Complete Guide To High-Performance Computing

Sagar Unagar shows why Accelerate is still one of Apple’s most underused frameworks, especially when naive loops start hurting apps that process signals, images, matrices, or large numeric datasets. The most useful part is the practical breakdown of vDSP, vForce, and BLAS, showing how vectorized system routines can replace manual iteration with code that is both clearer and dramatically faster.

How To Think About Performance In iOS

Artem Mirzabekian frames performance as a layered system, where perception, metrics, architecture, UI updates, networking, caching, scheduling, memory, and hardware all shape whether an app feels fast. The most useful takeaway is his order of attack: start with user-visible pain and measurement, then cut unnecessary work before reaching for low-level optimizations.

Coding 👨‍💻

Formatting Values In SwiftUI Text And TextField

Gabriel Theodoropoulos shows how SwiftUI’s format styles make Text and TextField much more powerful for numbers, percentages, currencies, and dates without manual string conversion. The most useful part is the input side: formatted TextField initializers can enforce valid numeric values automatically, while the stored type still controls how strict the field behaves.

SwiftUI: @State Under The Hood

Nikita Vasilev explains why @State survives view redraws even though SwiftUI views are value types: the real data lives outside the struct in SwiftUI’s long-lived Attribute Graph. The most useful part is the mental model shift, because it clarifies why @State should stay private, why init-based seeding often fails after first render, and how dependency tracking drives precise invalidation.

Apple 🍏

Brazilian Betting License Requirement For App Store Availability

Apple says fixed-odds betting apps can now be distributed on the App Store in Brazil, but only with a valid fixed-odds betting license from Brazil’s Secretariat of Prizes and Bets. The key practical detail is that developers must submit a new app version to start license verification, and answering “Yes” to the gambling question in App Store Connect sets the Brazil age rating to A18.

End-To-End Encrypted RCS Messaging Begins Rolling Out In Beta

Apple says end-to-end encrypted RCS is starting to roll out in beta for iPhone users on iOS 26.5 with supported carriers and Android users on the latest Google Messages. The most important user-facing detail is the new lock icon in RCS chats, with encryption enabled by default and expanding automatically to both new and existing conversations.

Other cool stuff 🧰

The CTO’s Incoming Storms

Etienne de Bruin maps six pressure points landing on CTOs right now, from AI-driven headcount cuts to board-level demands for an “AI strategy,” and argues that facts alone are no longer enough. The sharpest takeaway is to show up with a position built around trade-offs and business language, not a defensive technical rebuttal.

Finally Found A Use Case For .fixedSize

Omar Elsayed shows a neat SwiftUI layout trick where .fixedSize keeps an HStack inside a horizontal ScrollView only as tall as its tallest card, instead of expanding to the full screen.

AI 🤖

AI: When The More Rigorous Process Shipped The Lower-Quality Code

Dave Poirier compares two AI-assisted implementations of the same iOS telemetry feature and finds that the messier human-in-the-loop branch beat the stricter PRD-plus-TDD branch on testing depth, observability, and threading correctness. The sharpest takeaway is that spec-first AI workflows can stay too trapped inside their own frame, so production work still needs a separate pass for scope, integration edges, and operational gaps.

Agent View In Claude Code

Anthropic introduces agent view as a single place to manage multiple Claude Code sessions, with a list that shows which agents are waiting, still running, or finished. The most useful part is the workflow gain: you can background sessions, peek at the latest turn, reply inline, and jump between concurrent agents without juggling terminal tabs.

Tutorials 📒

SwiftData for Beginners

You will learn SwiftData through a small real app, starting from model design, source control, and local storage before moving into posts, images, navigation, and modern iOS 26 patterns. The most useful part is the beginner-friendly progression, where concepts like @Model, classes vs structs, optionals, and test data are introduced in the context of shipping an actual app.

Production SwiftUI: Scalable Networking Architecture With Async/Await And Generics

Karin Prater builds a reusable SwiftUI networking stack around services, endpoints, dependency injection, and concurrency-aware separation between UI state and background work. The most useful part is the architectural framing: keep observables focused on main-actor UI state, move fetch logic into sendable services, and use protocols plus mocks to make previews and scaling much easier.

Those Who Swift - Issue 265

Wed, 06 May 2026 20:32:23 GMT

Weekly note ✏️

AI is not only changing how we write software, but also how we get hired!

We all know about ATS systems scanning résumés and filtering candidates before a human even sees the application. But hiring automation is going much further now.

For years, some companies used prerecorded interview questions where candidates recorded answers by pressing a button. Later came the “tell us about yourself” intro videos to evaluate communication skills and readiness for remote work.

Now some AI-first companies are fully automating the interview process itself.

Imagine an AI interviewer. Let’s call her Clara. She starts politely with an ice-breaker like “How’s your day going?” and then moves into structured sections: Swift, APIs, Xcode, architecture. Sounds futuristic until the details appear. Clara asks candidates to leave a two-second pause after each answer so the system can detect when speech ends. Think too long, pause dramatically, or hesitate naturally, and your answer might simply get cut off.

Have a noisy environment? Better warn the birds outside, the construction workers nearby, or anyone making unexpected sounds. The system may interpret any loud noise as the end of your response. And Clara will not repeat questions, no matter how many times you ask.

Then comes the final stage: screen sharing and a coding challenge, often with strict instructions not to use AI tools. Which sounds ironic considering the company itself is using AI to evaluate and filter candidates from the very beginning.

Maybe that’s the strangest part of all. The process is optimized for efficiency, but in doing so it often removes the human side entirely. Instead of building interest in the company, it can have the opposite effect. Less time invested in candidates, more restrictions, more automation.

At this point, the real question almost sounds inevitable: will AI soon be interviewing AI?

Actors Vs Queues Vs Locks In Swift

Artem Mirzabekian compares three synchronization tools through the same lens: actors give the safest model for shared mutable state, queues fit older GCD-style coordination, and locks still matter when you need the lowest overhead. The most useful part is the tradeoff framing, because the right choice depends less on style and more on isolation needs, legacy code, and performance pressure.

Swift Concurrency: One await, Two Actors: A Runtime Trace

Nikita Galaganov explains what actually happens at runtime when Swift crosses an await, focusing on executor identity, suspension, continuation state, and executor hops between actors. The most useful part is the performance angle: the article shows that await is not just syntax sugar, and that understanding hop decisions matters when concurrency code runs at SDK scale across millions of devices.

Coding 👨‍💻

3 Key Strategies To Make SwiftUI Views More Reusable

Matteo Manferdini argues that most SwiftUI reuse problems start with monolithic views, then breaks the fix into three layers: extract small subviews, move shared styling into ViewModifier, and use generic container views when structure stays the same but content changes. The sharpest takeaway is his warning against computed properties as fake reuse, because they hide complexity inside the parent instead of creating truly testable, previewable, standalone components.

Scheduling And Handling Background App Refresh In SwiftUI

Natalia Panferova shows how to wire background refresh into a SwiftUI app with BGAppRefreshTaskRequest and the backgroundTask(_:action:) modifier, including the required capability and setup. The most useful reminder is that background refresh is opportunistic, not guaranteed, and should stay short-lived, with longer work pushed to other background APIs.

Managing Personal Projects With Agents

Felix Krause shows how personal AI agents can turn scattered project inputs from email, chat, and files into a cleaner system built around structured notes, linked source documents, and controlled automation. The most useful idea is the safety-conscious workflow: only manually approved inputs get processed, while the agent updates notes, organizes Google Drive files, and surfaces the latest version fast when you actually need it.

AI 🤖

AI Doesn’t Remember Your Project, Markdown Does

Alejandro makes a practical case for writing project context down in Markdown instead of expecting each new AI chat to rediscover architecture, constraints, and decisions from scratch. I could only verify the title and article snippet, so this summary is based on those visible details rather than the full post text.

iOS Privacy Manifest & Required Reasons APIs: A Compliance Checklist

Mrugesh Tank turns Apple’s privacy manifest rules into a practical checklist, with the clearest value coming from the five required-reason API categories that catch many teams by surprise, especially UserDefaults and system boot time calls. The most useful part is the concrete mapping from API category to allowed reason codes, plus a starter PrivacyInfo.xcprivacyexample you can adapt before App Store submission.

Video 🎥

My Take On The New Apple

Marques Brownlee sees Apple’s leadership change as more than a CEO swap, arguing that John Ternus could push the company back toward more ambitious, product-driven hardware decisions. The sharpest takeaway is the contrast: Apple may be ready to take bigger swings on devices again, but its software side still has a lot of ground to recover.

Apple Foundation Models With Mohammad Azam

This Swift Academy episode looks at Apple’s AI direction as an architectural shift, where models become native app capabilities instead of remote chat services. The most useful part is the framing around tools, structured generation, and adapter-based evolution, which makes Foundation Models feel more like controllable system components than generic AI features.

Books 📚

Algorithms

Jeff Erickson offers a free electronic version of his self-published algorithms textbook, plus a large set of lecture notes that go beyond the core material into topics like FFTs, linear programming, randomized algorithms, and models of computation. The most useful detail is the scope: this is not a beginner-first data structures book, but a deep reference for readers who already know the basics and want a more theory-heavy path.

Those Who Swift - Issue 264

Those Who Swift — Wed, 29 Apr 2026 20:26:55 GMT

Weekly note ✏️

Keeping a balance between resources, budget, and development output is crucial for teams of any size. The principle stays the same whether you are a solo developer or part of a large organization.

A recent example is Anthropic’s decision to make Opus 4.7 the default model for Claude Code starting April 30. Some organizations have already received emails notifying them about this change. The model promises better performance on complex tasks, but it also comes at a higher cost. While the company states that the tokenizer is more efficient and overall token usage should remain stable, real-world testing shows that limits can be reached quickly. At that point, you either slow down and continue manually or pay for additional tokens.

At the same time, social platforms are full of teams openly sharing monthly AI expenses in the range of thousands of dollars. That raises a practical question: at what point does it become more reasonable to invest in people instead of scaling token usage? Some experts already suggest that the so-called AI bubble may begin to stabilize later this year. Initial adoption has happened, workflows are established, and habits are formed. The next step is monetization, which often means higher prices and fewer ways to opt out of AI-driven tools.

For smaller companies, this becomes a real challenge. Being selective with tools, setting clear usage boundaries, and keeping part of the workflow independent from AI can help control costs and reduce risk.

And one more important thing worth mentioning: the App Store Small Business Program. It offers a reduced 15% commission on paid apps and in-app purchases.

Even years after its introduction, many developers are still unaware of it. If you qualify, it’s definitely something to look into.

When SwiftUI Modifiers Hold Onto Memory Longer Than Expected

Artem Mirzabekian points out that SwiftUI modifiers can keep reference-type dependencies alive longer than many developers expect, even after the view that used them seems gone. The useful takeaway is architectural: treat modifier-captured objects carefully, especially services or managers, because SwiftUI lifetime and storage behavior may not match the mental model of simple view recreation.

Immediate Tasks In Swift Concurrency Explained

Antoine van der Lee explains that Task.immediate starts running synchronously on the current executor until the first real suspension, which makes it useful for preserving ordering from synchronous actor-isolated code. The most useful warning is the tradeoff: if the first chunk of work is not tiny, immediate tasks can block the caller and even make task-group work accidentally serial.

Q&A: Swift Concurrency - Formatted

Post turns Apple’s live Swift Concurrency session into a cleaner, searchable transcript with timestamps, covering practical questions around MainActor, nonisolated, @concurrent, task cancellation, and actor usage. The most useful part is that it keeps the answers direct and grounded in real migration pain points, especially for teams moving toward newer Swift concurrency defaults.

Coding 👨‍💻

Enums. Swift’s Secret Superpower.

Will Lumley makes the case that Swift enums are far more than named constants, especially once you start using associated values, exhaustive switching, raw values, and enum-driven state. The most useful takeaway is architectural: enums can often replace class hierarchies, boolean-heavy view state, and weakly typed error handling with one safer, compiler-checked model.

Understanding Inout Parameters In Swift - How They Work And When To Use Them

Sagar Unagar reframes inout as an API design tool, not a performance trick, and shows why its real value is making mutation explicit and intentional. The most useful takeaway is the rule of thumb: prefer return values for pure transformations, and use inout only when in-place mutation is the whole point.

Apple 🍏

Monthly Subscriptions With A 12-Month Commitment

Apple is introducing a new App Store subscription option that lets customers pay monthly while committing to a full 12-month term, with payment progress visible in their Apple Account and reminders sent before renewals. The useful part for developers is that this can now be configured in App Store Connect and tested in Xcode, with broad rollout planned alongside the May releases of iOS 26.5 and related platforms.

Design 🎨

Appearance Mode Changer

Stewart Lynch shows a clean SwiftUI pattern for adding System, Light, and Dark mode selection with a small enum, @AppStorage, and preferredColorScheme applied at the app root. The most useful reminder is architectural: keep appearance as an app-level setting so navigation and sheets inherit it automatically without extra view-level logic.

Paywall Design Tips That Boost App Sales - Part 2

Daniils, the founder of AppLayouts, an extensive SwiftUI components library designed to help you build a perfect user interface for your iOS and macOS app in no time, is back with part two. He is sharing tips on broader topics related to paywalls and app monetization in general, based on what he has learned while testing different solutions in his own apps.

I Couldn’t Find The Perfect Browser, So I Built One With AI In Two Weeks

Omar Elsayed shares a very hands-on story of building a native WebKit browser with AI, while staying clear that AI worked best as a strong starting point, not as a replacement for product taste or engineering judgment. The most useful part is the prompt and architecture breakdown, showing how detailed guidance, clear constraints, and human refinement turned a rough idea into a real macOS app.

How To Implement Pagination With SwiftUI’s List View

Natascha Fadeeva shows a simple infinite scrolling pattern for List: add a loading row at the bottom and trigger the next page when that row appears. The most useful detail is the guardrail in loadMoreItems(), since repeated onAppear calls must not start overlapping pagination requests.

AI 🤖

Introducing GPT-5.5

OpenAI says GPT-5.5 is its strongest model yet for real work, with gains in agentic coding, computer use, knowledge work, and early scientific research while matching GPT-5.4 latency and using fewer tokens on some tasks. The most useful practical detail is availability: it started rolling out in ChatGPT and Codex on April 23, 2026, and OpenAI updated the post on April 24 to say GPT-5.5 and GPT-5.5 Pro are now available in the API too.

Customizing Claude Code Memory

Samwize explains where Claude Code stores auto memory, how it is scoped per repo or folder, and which settings can safely override the default location. The most useful tip is that related repos can share memory by pointing .claude/settings.local.json to the same directory, while project-level settings intentionally block redirection for safety.

Claude For Creative Work

Anthropic is positioning Claude as a creative workflow tool, adding connectors for Blender, Autodesk Fusion, Adobe, Ableton, SketchUp, Splice, and other apps creative teams already use. The most interesting part is the workflow angle: Claude can now help across ideation, scripting, asset pipelines, and repetitive production work instead of staying limited to chat.

Tutorials 📒

Concurrency Step-By-Step: Designing Protocols

Matt Massicotte shows how protocol design gets much trickier once Swift 6 isolation rules, @MainActor defaults, and conformance mismatches enter the picture. The most useful takeaway is that synchronous requirements are rigid, while async requirements, nonisolated, and carefully chosen protocol constraints can make conforming types much easier to design.

iOS 26 SDK Migration Guide: What Every App Needs To Update

Mrugesh Tank walks through the practical migration path for apps targeting the iOS 26 SDK, from Xcode 26 and deprecated APIs to Privacy Manifests, Liquid Glass, and regression testing. The most useful part is the checklist mindset: treat build warnings as migration tasks, then test UI, networking, and permission flows early before the App Store deadline hits.

VibeUI: 92 Free UI Prompts For Vibe Coders

VibeUI is a curated prompt library with 92 UI prompts across 15 categories, covering things like auth, pricing, hero sections, dashboards, onboarding, and more. The most useful part is the structure-first approach: you can pick a layout pattern, copy the prompt, and use it in tools like Claude, GPT-5, or Gemini to generate cleaner UI variants faster.

GPT Image 2 Prompts

YouMind has built a large prompt library for GPT Image 2, with more than 2,700 free image and video prompts across categories like infographics, app design, social posts, thumbnails, and posters. The most useful part is the structure: many prompts are written as reusable templates with arguments, which makes them easier to adapt for repeated creative work instead of starting from scratch every time.

Associatedtype In Swift Explained - A Complete Guide With SwiftUI Examples

Sagar Unagar explains associatedtype through the distinction that generics choose a type from the caller side, while associated types let the conforming type decide it.

SE-0526: WithDeadline

The Swift Evolution review introduces withDeadline, a concurrency API that cancels work when an absolute deadline passes, while still waiting for the operation to finish cooperatively rather than force-stopping it. The most debated part is the API shape itself, with much of the discussion focused on naming, typed error wrapping, and whether the cancellation behavior should be made more explicit in the name.

A Reusable Spotlight Onboarding Component In SwiftUI

Artem Mirzabekian builds a reusable SwiftUI onboarding spotlight that can highlight any view, show contextual guidance, and keep working across scroll views, navigation, sheets, and safe areas. The most useful part is the implementation approach: anchors and PreferenceKey make the solution flexible without dropping into UIKit-style overlay hacks.

Building A Draggable Bottom Sheet In SwiftUI

Natascha Fadeeva shows how to build a draggable bottom sheet with SwiftUI’s native sheet and presentationDetents, while still allowing scroll coordination and interaction with content underneath like a map. The most useful detail is that you can combine custom detents, disabled interactive dismissal, and background interaction for a bottom-sheet feel without building a fully custom container.

Tim Cook To Become Apple Executive Chairman, John Ternus To Become Apple CEO

Apple announced that Tim Cook will become executive chairman and John Ternus will become Apple CEO on September 1, 2026, marking the biggest leadership change at the company since Cook took over in 2011. The key detail for developers and the industry is that Ternus comes from hardware engineering, which may keep Apple’s product-first direction firmly in place during the transition.

Dotted Background Effect In Metal

Victor Baro breaks down an interactive dotted background shader step by step, showing how SDF circles, fract(), floor(), and touch-driven uniforms combine into glow, attraction, and repulsion effects. The most useful part is the mental model: dots are not moving objects, just pixel math, so the motion comes from shifting each dot’s logical center before rendering.

FormatStyle Guide

Chris Eidhof introduced an interactive browser-based guide to Swift Foundation’s FormatStyle APIs, with live examples for numbers, dates, measurements, and parsing. The most useful part is the SwiftUI angle, since the guide also shows how these formatters plug into real app code instead of staying as isolated API docs.

Five Things I Learned About Making AI Coding Agents Actually Work

Ivan Magda argues that better results from coding agents usually come from better scaffolding, not from switching models. The most useful takeaways are practical ones: keep instruction files short, structure projects so agents can navigate them, start fresh sessions earlier, and give the agent a way to verify its own work.

Introducing Claude Opus 4.7

Anthropic says Claude Opus 4.7 is now generally available, with stronger performance on difficult software engineering tasks, better vision, and more reliable long-running work than Opus 4.6. The practical detail is availability: it is live across Claude products, the API, Amazon Bedrock, Google Cloud Vertex AI, and Microsoft Foundry, with pricing unchanged from Opus 4.6.

Introducing Claude Design By Anthropic Labs

Anthropic says Claude Design lets teams create prototypes, slides, one-pagers, and other visual work through conversation, with support for inline edits, design systems, and exports to formats like PPTX, PDF, Canva, and HTML. The most interesting part is the workflow bridge: once a design is ready, it can be packaged into a handoff bundle for Claude Code, making the jump from idea to implementation much tighter.

Codex For (Almost) Everything

OpenAI says Codex is moving beyond coding into a wider developer workflow, with computer use, image generation, memory, repeatable automations, and support for tools like GitHub reviews, SSH devboxes, and browser-based iteration. The most useful part is the broader scope: it is starting to feel less like a code assistant and more like a workspace agent that can carry context across the full software development lifecycle.

SwiftUI: Refreshable Task Cancellation

Article explains a subtle SwiftUI trap where .refreshable can cancel its own work if state changes trigger a redraw too early. The most useful part is the two-fix breakdown: publish one final state update when possible, or wrap the refresh logic in a separate task when incremental updates are required.

Weekly note ✏️

While Anthropic is tightening control over its ecosystem by restricting third-party access tools like OpenClaw from its subscriptions to prevent overuse, another story is unfolding behind the scenes. Their upcoming model, Mythos, expected later this month, has reportedly been paused due to security concerns.

During early testing, the model was able to bypass guardrails and escape its sandbox. Ironically, a system designed for security research and penetration testing did exactly what it was built to do. That result raised serious concerns, even among its creators. The situation escalated enough that Anthropic partnered with a wide group of companies, including potential competitors, under Project Glasswing. The goal is clear: understand how to prevent future models from autonomously exploiting systems and instead keep them focused on safe, controlled tasks.

This highlights an important shift. As models become more capable, the challenge is no longer just performance or quality, but control and containment.

Meanwhile, on the other side of the bridge, the hiring market tells a very different story. AI-generated job descriptions are still filled with outdated requirements. Take-home assignments ask for UIKit and Combine implementations in 2026, often without third-party dependencies or modern layout tools. What exactly is being tested here? The ability to work under stress, or the willingness to ignore years of progress?

Development should not feel like driving on unbalanced wheels. If a company is not explicitly hiring for maintaining legacy systems, it’s worth thinking twice before investing time in such unpaid tasks. Your time is valuable, and the tools you choose should reflect the present, not the past.

Lazy Properties In Swift - Why They Don’t Always Work In SwiftUI

Sagar Unagar explains that lazy is useful for deferred and cached initialization, but it becomes misleading inside SwiftUI views because view structs are recreated often and body is non-mutating. The most useful takeaway is practical: keep lazyfor class-based objects with stable identity, and use @State or @StateObject when SwiftUI lifecycle control matters.
