SwiftBindings.Apple.WorkoutKit

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#.

Installation

dotnet add package SwiftBindings.Apple.WorkoutKit

Requirements

• .NET 10.0+
• iOS 26.2+, macOS 26.2+, Mac Catalyst 26.2+
• 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.AuthorizationStateType.Authorized;
// var maxScheduled = WorkoutScheduler.Shared.MaxAllowedScheduledWorkoutCount;
// var isSupported = WorkoutScheduler.IsSupported;

// Build workout primitives
var step = new IntervalStep(IntervalStep.PurposeType.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.
