# TabContent A type that provides content for programmatically selectable tabs in a tab view. ``` @MainActor @preconcurrency protocol TabContent ``` ## 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 } ``` ## Topics ### Setting tab content [`var body: Self.Body`](/documentation/SwiftUI/TabContent/body-swift.property) The value of this type’s nested content.
