Widgetkit

This is the reference you want when building any kind of widget for iOS. It covers the full spectrum: home screen widgets with timeline providers, Lock Screen accessories, Live Activities with Dynamic Island layouts, and the newer Control Center widgets in iOS 18. The workflow sections are practical, walking through extension setup, App Groups, and the distinction between StaticConfiguration and AppIntentConfiguration. Interactive widgets get proper treatment with Button and Toggle patterns using AppIntent. The family adaptation examples and timeline policy guidance are immediately useful. It assumes you know SwiftUI but explains the WidgetKit-specific pieces clearly, including the async AppIntentTimelineProvider versus the callback-based TimelineProvider.
