PrimitiveButtonStyle

protocol · iOS 13.0+ · SDK 27.1

@MainActor @preconcurrency protocol PrimitiveButtonStyle

A type that applies custom interaction behavior and a custom appearance to all buttons within a view hierarchy. To configure the current button style for a view hierarchy, use the ``View/buttonStyle(_:)`` modifier. Specify a style that conforms to `PrimitiveButtonStyle` to create a button with custom interaction behavior. To create a button with the standard button interaction behavior defined for each platform, use ``ButtonStyle`` instead. 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 }
