# TemporalSequence Async sequence for temporal features. ``` protocol TemporalSequence : AsyncSequence ``` ## Topics ### Getting the sequence count [`var count: Int?`](/documentation/CreateMLComponents/TemporalSequence/count) The number of elements in the sequence if available, calculated nondestructively. ### Associating the types [`associatedtype Feature`](/documentation/CreateMLComponents/TemporalSequence/Feature) The feature type. ## Relationships ### Conforming Types [`CumulativeSumSequence`](/documentation/CreateMLComponents/HumanBodyActionCounter/CumulativeSumSequence) [`FeatureSequence`](/documentation/CreateMLComponents/AudioFeaturePrint/FeatureSequence) [`PreprocessedFeatureSequence`](/documentation/CreateMLComponents/PreprocessedFeatureSequence) [`DownStreamSequence`](/documentation/CreateMLComponents/Downsampler/DownStreamSequence) [`CameraAsyncBuffers`](/documentation/CreateMLComponents/VideoReader/CameraAsyncBuffers) [`MicrophoneAsyncBuffers`](/documentation/CreateMLComponents/AudioReader/MicrophoneAsyncBuffers) [`AsyncFrames`](/documentation/CreateMLComponents/VideoReader/AsyncFrames) [`AsyncBuffers`](/documentation/CreateMLComponents/AudioReader/AsyncBuffers) [`WindowSequence`](/documentation/CreateMLComponents/SlidingWindowTransformer/WindowSequence) [`AnyTemporalSequence`](/documentation/CreateMLComponents/AnyTemporalSequence) ### Inherits From [`AsyncSequence`](/documentation/Swift/AsyncSequence) --- Copyright © 2026 Apple Inc.
