# AccessibilityRotorContent Content within an accessibility rotor. ``` @MainActor @preconcurrency protocol AccessibilityRotorContent ``` ## Overview Generally generated from control flow constructs like `ForEach` and `if`, and `AccessibilityRotorEntry`. 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 ### Supporting types [`body`](/documentation/SwiftUI/AccessibilityRotorContent/body-swift.property) The internal content of this `AccessibilityRotorContent`.
