# ControlGroupStyle

Defines the implementation of all control groups within a view hierarchy.

## Declaration

```swift
@MainActor @preconcurrency protocol ControlGroupStyle
```

## Overview

Overview To configure the current ControlGroupStyle for a view hierarchy, use the controlGroupStyle(_:) modifier. 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 }
