Models

The DocC archive exposes model-level symbols used by controller APIs and callbacks.

Session persistence models

SaveWorkoutState is the central payload received by saveSession(state:).

High-signal properties documented in DocC include:

• startDate, duration, calories
• blocks, filteredBlocks, exercises
• exerciseEvaluations, difficultyChanges, weightDifficulties
• equipmentWeights, healthEvaluation, names

Media models

Type	Key members
Video	url
VideoMetadata	cover, coverSize, title, subtitle, timeRange, relativeProgress(from:)

These models are primarily used by StreamingWorkoutController and remote media integrations.

Exercise and workout mode models

Type	Notes
BlockExercise	Includes identifier, effortType, value.
ExerciseEvaluation	Includes identifier, blockId, duration, repetitions, choice, exerciseMaxReferenceValue.
ExerciseType	Enum with calibration(_), duration, repetition.
WorkoutStateMode	Enum for workout UI state: launcher, start, ongoing, paused, finished, stopped, notStarted.
ChronoState	Timer/countdown state used by workout flow rendering. Includes value (TimeInterval) and referenceDate (TimeInterval), plus the .stopwatch(value:referenceDate:) factory.

Remote playback models

Type	Notes
RemoteMediaPlayerState	Enum with loading, buffering, playing, paused, idle, unknown.
RemoteManager / RemoteManagerDelegate	Model/controller bridge for remote session state.

Supporting symbols

DocC also includes integration support symbols for Apple Watch and session-level communication: SessionDelegater (declared once, in the shared TrainingKitShared module, used by both the iOS and Watch targets) and SessionGateway.shared — note this is two distinct types with the same name, one defined in the iOS TrainingKit module and a separate one defined in TrainingKitWatch, not a single symbol shared across platforms.

Use the DocC archive as canonical source for exact signatures, conformance details, and per-member discussions.
