FormStyle

protocol · iOS 16.0+ · SDK 27.1

@MainActor @preconcurrency protocol FormStyle

The appearance and behavior of a form. To configure the style for a single ``Form`` or for all form instances in a view hierarchy, use the ``View/formStyle(_:)`` 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 }
