Which iOS versions are covered by this skill?

It covers modern UIKit patterns back-deployed to iOS 13 and includes support for the latest APIs up to iOS 26, ensuring forward compatibility.

Does it enforce a specific app architecture?

No, it focuses on native API best practices and performance-conscious patterns rather than mandating specific architectures like MVVM, VIPER, or Coordinators.

Does this skill support SwiftUI?

The skill focuses primarily on UIKit but includes specific patterns for UIKit-SwiftUI interoperability, such as using UIHostingController and UIHostingConfiguration.

How does it help with Auto Layout performance?

It enforces best practices like batching constraint activation, avoiding layout churn, and using UIKeyboardLayoutGuide instead of manual notification handling.
