# Commands

Conforming types represent a group of related commands that can be exposed to the user via the main menu on macOS and key commands on iOS.

## Declaration

```swift
@MainActor @preconcurrency protocol Commands
```

## Mentioned in

Building and customizing the menu bar with SwiftUI

## Overview

Overview A type conforming to this protocol inherits @preconcurrency @MainActor isolation from the protocol if the conformance is included in the type’s base declaration: struct MyCustomType: Transition {     // `@preconcurrency @MainActor` isolation by default } Isolation to the main actor is the default, but it’s not required. Declare the conformance in an extension to opt out of main actor isolation: extension MyCustomType: Transition {     // `nonisolated` by default }
