Those Who Swift - Issue 208
Your weekly dose of Swift!
Weekly note ✏️
AI, vibe-coding, WWDC—there’s no shortage of trends in tech. But at the end of the day, if you want to build solid software, you either go Indie (a whole different world, which we’ll cover later) or work for a company.
And when you work for a company, beyond your hard skills, you need to keep an eye out for red flags that should make you reconsider your choices early on. Some common ones include:
🚩 Unrealistic goals – “We’re going to disrupt the market!” (without a clear plan).
🚩 Non-standard working schemes – No fixed salary date, accountants ignoring you while your bank waits for payment details.
🚩 Lies about financial and legal matters – No signed contracts with investor and partners, missing licenses for required work.
🚩 Non-professional leadership – Jokes about “getting fit without a salary” instead of solving actual problems.
Value yourself. Don’t let a company take advantage of you beyond what’s outlined in your contract.
Honestly, I’ve been wondering—companies can fire employees if they fail to do their job. Wouldn’t it be fair if the reverse applied? If a company consistently fails to meet its promises, shouldn’t the leadership step down for mismanagement? Food for thought.

Does AsyncStream Replace Combine? No.
Michael Long examines the roles of AsyncStream and Combine in Swift, concluding that while AsyncStream offers a modern syntax for handling asynchronous sequences, it doesn't fully replace Combine. He highlights that Combine remains more efficient for modeling ongoing streams of values, especially in complex scenarios requiring advanced operators and backpressure handling.

There is no Vibe Engineering
Sergey Tselovalnikov challenges the idea of "vibe coding," where developers rely on AI agents to generate code. While useful for prototyping, he argues it lacks the depth of real software engineering, which involves scalability, security, and maintainability. AI can assist coding, but it doesn’t replace true engineering.
