# withMLTensorComputePolicy(_:_:) Calls the given closure within a task-local context using the specified compute policy to influence what compute device tensor operations are executed on. ``` func withMLTensorComputePolicy(_ computePolicy: MLComputePolicy, _ body: () async throws -> R) async rethrows -> R ``` ## Parameters `computePolicy` A compute policy that will be set before the closure gets called and restored after the closure returns. `body` A nullary closure. If the closure has a return value, that value is also used as the return value of the `withMLTensorComputePolicy(_:_:)` function. ## Return Value The return value, if any, of the `body` closure. --- Copyright © 2026 Apple Inc.
