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.
