# SlidingWindowTransformer A temporal transformer that groups input elements. ``` struct SlidingWindowTransformer where Input : Sendable ``` ## Topics ### Creating a transformer [`init(stride: Int, length: Int)`](/documentation/CreateMLComponents/SlidingWindowTransformer/init(stride:length:)) Creates a window temporal transformer. ### Getting the properties [`let length: Int`](/documentation/CreateMLComponents/SlidingWindowTransformer/length) The length of a window. [`let stride: Int`](/documentation/CreateMLComponents/SlidingWindowTransformer/stride) The number of elements between the start of two consecutive windows. ### Performing the transformation [`func applied(to: S, eventHandler: EventHandler?) throws -> SlidingWindowTransformer.WindowSequence`](/documentation/CreateMLComponents/SlidingWindowTransformer/applied(to:eventHandler:)) Extracts a window sequence from the input sequence [`struct WindowSequence`](/documentation/CreateMLComponents/SlidingWindowTransformer/WindowSequence) An async sequence of windows. ## Relationships ### Conforms To [`Sendable`](/documentation/Swift/Sendable) [`Decodable`](/documentation/Swift/Decodable) [`Encodable`](/documentation/Swift/Encodable) [`TemporalTransformer`](/documentation/CreateMLComponents/TemporalTransformer) [`SendableMetatype`](/documentation/Swift/SendableMetatype) --- Copyright © 2026 Apple Inc.
