# PreprocessedFeatureSequence An asynchronous sequence of eagerly stored temporal features. ``` struct PreprocessedFeatureSequence ``` ## Overview This sequence eagerly stores the results of preprocessing a temporal estimator. ## Topics ### Creating a sequence [`init(S) async throws`](/documentation/CreateMLComponents/PreprocessedFeatureSequence/init(_:)) Creates an asynchronous sequence of stored temporal features. ### Getting the properties [`var count: Int?`](/documentation/CreateMLComponents/PreprocessedFeatureSequence/count) The stored temporal feature count. [`var features: [TemporalFeature]`](/documentation/CreateMLComponents/PreprocessedFeatureSequence/features) The stored temporal features. ## Relationships ### Conforms To [`TemporalSequence`](/documentation/CreateMLComponents/TemporalSequence) [`AsyncSequence`](/documentation/Swift/AsyncSequence) --- Copyright © 2026 Apple Inc.
