Critical Rules (Low Freedom)
Performance
- NO
Ti.UI.SIZE in ListViews: Causes jerky scrolling. Use fixed heights.
- Prefer ListView over TableView for new apps with large datasets.
- Batch updates: Use
applyProperties to reduce bridge crossing overhead.
- WebView in TableView: Anti-pattern causing severe scrolling issues.
iOS Accessibility
- NO accessibility properties on container views: Blocks children interaction.
- NO accessibilityLabel on text controls (Android): Overrides visible text.
Layout
- Use
dp units for cross-platform consistency.
- Android ScrollView: Vertical OR horizontal, not both. Set
scrollType.
Event Management
- Remove global listeners (
Ti.App, Ti.Gesture, Ti.Accelerometer) on pause to save battery.
- Event bubbling: Input events bubble up; system events do not.
App Architecture
- Limit tabs to 4 or less for better UX across platforms.
- Use NavigationWindow for iOS hierarchical navigation.
- Handle androidback to prevent unexpected app exits.

UI Design Workflow
- Choose App Structure: Tab-based (most common) or Window-based
- Layout Selection: Choose mode (composite/vertical/horizontal) based on structure
- Sizing Strategy: Assign
SIZE or FILL based on component defaults
- Event Architecture: Plan bubbling, app-level events, lifecycle
- Performance: Use ListView/TableView templates, batch updates
- Accessibility: Apply a11y properties per platform requirements
- Motion: Add animations, 2D/3D transforms, transitions
