What is apple-platforms?

This Claude skill streamlines Apple platform development by providing optimized SwiftUI code patterns and platform-specific implementations for macOS, iPadOS, watchOS, and visionOS. It enables developers to quickly generate boilerplate and logic for everything from menu bar utilities and adaptive iPad layouts to immersive spatial computing experiences and health-tracking apps, ensuring best practices across the Apple ecosystem.

When should I use apple-platforms?

apple-platforms is useful in the following scenarios: • Developing macOS menu bar applications with custom status items, window styles, and system-integrated commands. • Implementing adaptive layouts for iPadOS that seamlessly transition between compact slide-over and full-screen split views. • Building watchOS fitness applications with HealthKit integration for real-time workout tracking and heart rate monitoring. • Creating immersive 3D spatial experiences and RealityKit integrations for visionOS using volumes and immersive spaces. • Managing multi-platform codebases efficiently using conditional compilation and platform-specific type aliases to share logic across devices.

Apple Platform Development

macOS Specifics

@main
struct MacApp: App {
    var body: some Scene {
        // Main window
        WindowGroup {
            ContentView()
        }
        .windowStyle(.hiddenTitleBar)
        .windowToolbarStyle(.unified(showsTitle: true))
        .defaultSize(width: 900, height: 600)
        .commands {
            CommandGroup(replacing: .newItem) {
                Button("New Document") { }
                    .keyboardShortcut("n", modifiers: .command)
            }
            ToolbarCommands()
        }

        // Menu bar app
        MenuBarExtra("Status", systemImage: "star.fill") {
            Button("Preferences...") { openSettings() }
            Divider()
            Button("Quit") { NSApp.terminate(nil) }
        }
        .menuBarExtraStyle(.window)

        // Settings window
        Settings {
            SettingsView()
        }
    }
}

iPadOS Adaptive Layouts

struct AdaptiveView: View {
    @Environment(\.horizontalSizeClass) var sizeClass

    var body: some View {
        if sizeClass == .compact {
            // iPhone or iPad slide-over
            TabView {
                HomeTab()
                SearchTab()
            }
        } else {
            // iPad full screen
            NavigationSplitView {
                Sidebar()
            } detail: {
                DetailView()
            }
        }
    }
}

// Keyboard shortcuts for iPad
struct ContentView: View {
    var body: some View {
        List { }
            .keyboardShortcut("f", modifiers: .command)
            .focusable()
    }
}

watchOS

@main
struct WatchApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

// Workout tracking
class WorkoutManager: NSObject, ObservableObject {
    private var session: HKWorkoutSession?
    private var builder: HKLiveWorkoutBuilder?
    @Published var heartRate: Double = 0

    func startWorkout(type: HKWorkoutActivityType) async throws {
        let config = HKWorkoutConfiguration()
        config.activityType = type
        config.locationType = .outdoor

        session = try HKWorkoutSession(
            healthStore: HKHealthStore(),
            configuration: config
        )
        builder = session?.associatedWorkoutBuilder()
        session?.startActivity(with: .now)
        try await builder?.beginCollection(at: .now)
    }
}

visionOS Spatial Computing

@main
struct VisionApp: App {
    var body: some Scene {
        // 2D window
        WindowGroup {
            ContentView()
        }

        // 3D volume
        WindowGroup(id: "globe") {
            Globe3DView()
        }
        .windowStyle(.volumetric)
        .defaultSize(width: 0.5, height: 0.5, depth: 0.5, in: .meters)

        // Immersive space
        ImmersiveSpace(id: "solar-system") {
            SolarSystemView()
        }
        .immersionStyle(selection: .constant(.mixed), in: .mixed)
    }
}

// RealityKit integration
struct ImmersiveView: View {
    var body: some View {
        RealityView { content in
            let sphere = ModelEntity(mesh: .generateSphere(radius: 0.1))
            sphere.position = [0, 1.5, -1]
            content.add(sphere)
        }
        .gesture(TapGesture().targetedToAnyEntity())
    }
}

Multi-Platform Code

#if os(iOS)
typealias PlatformColor = UIColor
#elseif os(macOS)
typealias PlatformColor = NSColor
#endif

// Conditional compilation
struct ContentView: View {
    var body: some View {
        #if os(watchOS)
        CompactView()
        #elseif os(tvOS)
        LargeDisplayView()
        #else
        StandardView()
        #endif
    }
}
