iOS UI & Layout Standards

Priority: P0

Implementation Guidelines

Auto Layout

Code-Based Layout: Prefer programmatic layout using NSLayoutAnchor or SnapKit over Storyboards for better source control.
Safe Area: Always respect view.safeAreaLayoutGuide.
UIStackView: Use for linear layouts to reduce constraint complexity.

UIKit Best Practices

View Lifecycle: Perform layout adjustments in viewWillLayoutSubviews or updateConstraints.
Reusable Views: Extract complex UI into custom UIView subclasses.
Image Optimization: Use SF Symbols for icons. Preferred vector (PDF/SVG) for custom assets.
SwiftUI Bridge: Use UIViewRepresentable or UIViewControllerRepresentable to host UIKit in SwiftUI.

Human Interface Guidelines (HIG)

Accessibility: Support Dynamic Type and provide meaningful accessibilityLabel.
Feedback: Use UINotificationFeedbackGenerator for haptic feedback on actions.
Margins: Follow standard system margins (typically 16-20pt).

Anti-Patterns

No CGRect(x:y:w:h): Use Auto Layout.
No complex constraint logic in VC: Use UIStackView or custom views.
No Blank Screens: Use skeleton views or UIActivityIndicatorView.
