How do I build a watchOS app and complications?

Building a watchOS app and implementing complications involves various steps, including setting up the project, designing the user interface, and coding the functionality of the app.

// Example of creating a simple watchOS app import WatchKit import SwiftUI @main struct MyWatchApp: App { var body: some Scene { WindowGroup { ContentView() .navigationTitle("My Watch App") } } } struct ContentView: View { var body: some View { Text("Hello, watchOS!") .font(.largeTitle) .padding() } }

Complications are small widgets that show information from your app on the watch face. To create a complication, you must implement a complication controller and provide the necessary data.

// Example of a simple complication import ComplicationKit class ComplicationController: NSObject, CLKComplicationDataSource { // Implement the required methods for CLKComplicationDataSource func getCurrentTimelineEntry(for complication: CLKComplication, withHandler: @escaping (CLKComplicationTimelineEntry?) -> Void) { // Provide current data for the complication let entry = CLKComplicationTimelineEntry(date: Date(), complicationTemplate: /* your template here */) withHandler(entry) } }
