# transaction(_:body:) Applies the given transaction mutation function to all animations used within the `body` closure. ``` nonisolated func transaction(_ transform: @escaping (inout Transaction) -> Void, @ContentBuilder body: (PlaceholderContentView) -> V) -> some View where V : View ``` ## Discussion Any modifiers applied to the content of `body` will be applied to this view, and the changes to the transaction performed in the `transform` will only affect the modifiers defined in the `body`. The following code animates the opacity changing with a faster animation, while the contents of MyView are animated with the implicit transaction: ``` MyView(isActive: isActive) .transaction { transaction in transaction.animation = transaction.animation?.speed(2) } body: { content in content.opacity(isActive ? 1.0 : 0.0) } ``` - See Also: `Transaction.disablesAnimations` --- Copyright © 2026 Apple Inc.
