# AnnotatedBatch A batch of annotated examples for fitting a supervised estimator. ``` struct AnnotatedBatch where Scalar : MLShapedArrayScalar ``` ## Topics ### Creating an annotated batch [`init(features: MLShapedArray, annotations: MLShapedArray)`](/documentation/CreateMLComponents/AnnotatedBatch/init(features:annotations:)) Creates an annotated batch. ### Inspecting an annotated batch [`var annotations: MLShapedArray`](/documentation/CreateMLComponents/AnnotatedBatch/annotations) The shaped array of annotations. [`var count: Int`](/documentation/CreateMLComponents/AnnotatedBatch/count) The number of examples in the batch. [`var features: MLShapedArray`](/documentation/CreateMLComponents/AnnotatedBatch/features) The shaped array of features. ## Relationships ### Conforms To [`Decodable`](/documentation/Swift/Decodable) [`Escapable`](/documentation/Swift/Escapable) [`Equatable`](/documentation/Swift/Equatable) [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`Copyable`](/documentation/Swift/Copyable) [`Encodable`](/documentation/Swift/Encodable) [`Sendable`](/documentation/Swift/Sendable) --- Copyright © 2026 Apple Inc.
