# InferenceFunction.MutableViews A collection of `InferenceValue.MutableView`s which can be updated in-place by an `InferenceFunction`. ``` struct MutableViews ``` ## Topics ### Creating a collection [`init()`](/documentation/CoreAI/InferenceFunction/MutableViews/init()) Initialize an empty instance. ### Adding views [`func insert(inout some InferenceValue.MutableViewRepresentable & ~Copyable, for: String)`](/documentation/CoreAI/InferenceFunction/MutableViews/insert(_:for:)-1b2yx) Insert a new value to the output views. [`func insert(consuming NDArray.MutableView, for: String)`](/documentation/CoreAI/InferenceFunction/MutableViews/insert(_:for:)-8ossp) Insert the mutable view to be used as the ndArray value named `name`. [`func insert(consuming NDArray.MutableRawView, for: String)`](/documentation/CoreAI/InferenceFunction/MutableViews/insert(_:for:)-9ixpc) Insert the mutable view for the value named `name`. --- Copyright © 2026 Apple Inc.
