ios-watchos

Purpose

This skill enables development of watchOS apps using Swift and Apple's frameworks, focusing on WidgetKit for complications, WatchConnectivity for device syncing, SwiftUI for interfaces, HealthKit for health data access, and OpenClaw Watch extensions for custom features.

When to Use

Use this skill for building watchOS apps that need dynamic complications (e.g., updating timelines), real-time data transfer from iOS devices, custom SwiftUI layouts on the Watch, querying health metrics like workouts, or integrating OpenClaw for extended functionality. Apply it in scenarios like fitness tracking apps or notification-based tools.

Key Capabilities

• WidgetKit complications: Create timeline-based updates for watch faces, e.g., using TimelineProvider to refresh data every 15 minutes.
• WatchConnectivity: Establish sessions for sending/receiving data between iOS and watchOS, handling transfers up to 100KB per message.
• SwiftUI on Watch: Build responsive interfaces with components like NavigationView and List, optimized for small screens (e.g., 44mm display).
• HealthKit: Access health data types such as HKWorkout and HKQuantityTypeStepCount, with background delivery for real-time updates.
• OpenClaw Watch extension: Leverage custom APIs for enhanced app features, requiring authentication via $OPENCLAW_API_KEY for secure connections.
