# TabViewStyle

A specification for the appearance and interaction of a tab view.

```
@MainActor @preconcurrency protocol TabViewStyle
```

## 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
}
```
