# transition(_:) Associates a transition with the view. ``` @export(implementation) nonisolated func transition(_ transition: T) -> some View where T : Transition ``` ## Discussion When this view appears or disappears, the transition will be applied to it, allowing for animating it in and out. The following code will conditionally show MyView, and when it appears or disappears, will use a custom RotatingFadeTransition transition to show it. ``` if isActive { MyView() .transition(RotatingFadeTransition()) } Button("Toggle") { withAnimation { isActive.toggle() } } ``` --- Copyright © 2026 Apple Inc.
