STACK — Swift iOS (UIKit / SwiftUI hybrid)

Use for platform-native iOS UI — this is the only sane choice for iOS.

UIKit vs SwiftUI:

  • SwiftUI for new screens by default (iOS 16+ targets). Wrap UIKit views via UIViewRepresentable only when SwiftUI has no equivalent (AVKit camera, ARKit, MapKit gestures).
  • UIKit required for: deep UITextInput custom protocols, scroll-view precise tracking, UIPageViewController paging animations < 60 fps on SwiftUI.

App lifecycle:

  • @main struct App or AppDelegate/SceneDelegate pair. NOT both — pick one.
  • LaunchScreen.storyboard required (Info.plist key UILaunchStoryboardName) — Apple rejects static image launch.

Info.plist mandatory keys:

  • NSCameraUsageDescription / NSPhotoLibraryUsageDescription / NSLocationWhenInUseUsageDescription — if capability used; missing → runtime crash, not build error.
  • CFBundleURLTypes for custom URL schemes (deeplinks).
  • NSAppTransportSecurity — never set NSAllowsArbitraryLoads=true in prod (App Store rejection).
  • UIBackgroundModes array for any background audio / location / BLE.

Threading: @MainActor for UI mutation; actor for shared mutable state; Task { ... } for async. NO DispatchQueue.main.async wrapping UI updates from Swift Concurrency code (defeats actor isolation).

Forbidden: NSAllowsArbitraryLoads=true, force-unwrapping UIImage(named:) (use failable init), hardcoded API keys in .swift sources (use .xcconfig + Bundle.main.infoDictionary).
