# UnsafeSendable

A type whose values can safely be passed across concurrency domains by copying, but which disables some safety checking at the conformance site.

## Declaration

```swift
protocol UnsafeSendable : Sendable
```

## Overview

Overview Use an unchecked conformance to Sendable instead — for example: struct MyStructure: @unchecked Sendable { ... }
