Those Who Swift - Issue 203
Your weekly dose of Swift!
Weekly note ✏️
The discussion around the best data-slicing pattern always seems to land in the same category as debates over dark vs. light themes or the best code editor—everyone has strong opinions shaped by their experience with different architectures.
Whether it’s MVC, MVP, MVI, MVVM, VIPER, or RIB, there’s no one-size-fits-all solution—each exists to address specific needs.
Want to keep things simple with SwiftUI by storing state only within Views? Go for it. Need a large, testable module with shared behavior across Views? MVVM or VIPER might be a better fit. Finding the right balance between maintainability and scalability is a skill that grows with experience. In the end, just choose what benefits your project the most.

Tapping on Stack Views
Keith Harrison explains that applying gestures directly to stack views can lead to unexpected behavior, as only the areas occupied by the stack's subviews are tappable. By utilizing contentShape, developers can define a tappable area for the entire stack, ensuring consistent gesture recognition across the intended region. This approach enhances the user experience by making the entire stack view responsive to taps.
