SwiftBindings.Apple.WorkoutKit 26.2.13

SwiftBindings.Apple.WorkoutKit

Native .NET bindings for Apple's WorkoutKit framework — building custom workouts, single-goal and pacer workouts, interval blocks, and scheduling them to Apple Watch. These are not Objective-C proxy wrappers; they use .NET 10's native Swift interop for direct, high-performance calls into Swift APIs from C#.

📖 Full usage guide → — goals, steps, interval blocks, alerts, the four workout types, plans, and scheduling, with the exact emitted C# signatures.

Installation

dotnet add package SwiftBindings.Apple.WorkoutKit

Requirements

• .NET 10.0+
• Target framework: net10.0-ios26.2 (or -macos26.2 / -maccatalyst26.2) or higher. The package is compiled against the iOS 26.2 SDK supplement, so your app's <TargetFramework> platform version must be ≥ 26.2 to restore it — an explicit lower TPV (e.g. net10.0-ios18.0) or a bare net10.0-ios whose installed workload defaults below 26.2 fails restore with NU1202. This is the compile-SDK pin, not your app's deployment minimum.
• Deployment minimum is separate — set your app's real minimum OS with <SupportedOSPlatformVersion> (independent of the TFM above). Individual APIs that need a newer OS at runtime are gated by generated [SupportedOSPlatform] attributes; the C# compiler flags a call that isn't valid for your target.
• macOS host for development
• A paired Apple Watch and the companion watchOS app for scheduling to actually deliver

Usage

using WorkoutKit;

// Inspect scheduler authorization and capability
var status = WorkoutScheduler.AuthorizationStateKind.Authorized;
// var maxScheduled = WorkoutScheduler.Shared.MaxAllowedScheduledWorkoutCount;
// var isSupported = WorkoutScheduler.IsSupported;

// Build workout primitives
var step = new IntervalStep(IntervalStep.PurposeKind.Work);

CustomWorkout, SingleGoalWorkout, PacerWorkout, SwimBikeRunWorkout, IntervalBlock, IntervalStep, WorkoutPlan, ScheduledWorkoutPlan, the alert types, and WorkoutScheduler are all bound. See Apple's documentation for the full builder/scheduling flow.

Caveats

WorkoutScheduler (Shared, MaxAllowedScheduledWorkoutCount, IsSupported, ScheduleAsync) is bound and exercised end-to-end. HealthKit-backed writes are out-of-scope for this SDK version — the scheduler can schedule workouts, but mutating HealthKit data models from the bound surface is not yet supported.

How It Works

These bindings are auto-generated by Swift Dotnet Bindings using .NET 10's native Swift interop via the SwiftBindings SDK.
