# MLModelTransformerAdaptor A transformer that uses a Core ML model. ``` struct MLModelTransformerAdaptor where Scalar : MLShapedArrayScalar, Scalar : BinaryFloatingPoint ``` ## Topics ### Creating an adaptor [`init(model: MLModel) throws`](/documentation/CreateMLComponents/MLModelTransformerAdaptor/init(model:)) Creates a model adaptor from an MLModel. [`init(contentsOf: URL, configuration: MLModelConfiguration) throws`](/documentation/CreateMLComponents/MLModelTransformerAdaptor/init(contentsOf:configuration:)) Creates a model adaptor from a CoreML model URL. ### Getting the model [`let model: MLModel`](/documentation/CreateMLComponents/MLModelTransformerAdaptor/model) The CoreML model. ### Performing the transformation [`func applied(to: MLShapedArray, eventHandler: EventHandler?) async throws -> MLShapedArray`](/documentation/CreateMLComponents/MLModelTransformerAdaptor/applied(to:eventHandler:)) Performs a transformation on a single input. ## Relationships ### Conforms To [`Transformer`](/documentation/CreateMLComponents/Transformer) --- Copyright © 2026 Apple Inc.
