# transaction(_:)

Applies the given transaction mutation function to all animations used within the view.

## Declaration

```swift
nonisolated func transaction(_ transform: @escaping (inout Transaction) -> Void) -> some View

```

## Parameters

- `transform`: The transformation to apply to transactions within this view.

## Return Value

Return Value A view that wraps this view and applies a transformation to all transactions used within the view.

## Discussion

Discussion Use this modifier to change or replace the animation used in a view. Consider three identical animations controlled by a button that executes all three animations simultaneously: The first animation rotates the “Rotation” Text view by 360 degrees. The second uses the transaction(_:) modifier to change the animation by adding a delay to the start of the animation by two seconds and then increases the rotational speed of the “Rotation\nModified” Text view animation by a factor of 2. The third animation uses the transaction(_:) modifier to replace the rotation animation affecting the “Animation\nReplaced” Text view with a spring animation. The following code implements these animations: struct TransactionExample: View {     @State private var flag = false

var body: some View {         VStack(spacing: 50) {             HStack(spacing: 30) {                 Text("Rotation")                     .rotationEffect(Angle(degrees:                                             self.flag ? 360 : 0))

Text("Rotation\nModified")                     .rotationEffect(Angle(degrees:                                             self.flag ? 360 : 0))                     .transaction { view in                         view.animation =                             view.animation?.delay(2.0).speed(2)                     }

Text("Animation\nReplaced")                     .rotationEffect(Angle(degrees:                                             self.flag ? 360 : 0))                     .transaction { view in                         view.animation = .interactiveSpring(                             response: 0.60,                             dampingFraction: 0.20,                             blendDuration: 0.25)                     }             }

Button("Animate") {                 withAnimation(.easeIn(duration: 2.0)) {                     self.flag.toggle()                 }             }         }     } } Use this modifier on leaf views such as Image or Button rather than container views such as VStack or HStack. The transformation applies to all child views within this view; calling transaction(_:) on a container view can lead to unbounded scope of execution depending on the depth of the view hierarchy.
