# default A default animation instance. ``` static let `default`: Animation ``` ## Discussion The `default` animation is [`spring(response:dampingFraction:blendDuration:)`](/documentation/SwiftUI/Animation/spring(response:dampingFraction:blendDuration:)) with: - `response` equal to `0.55` - `dampingFraction` equal to `1.0` - `blendDuration` equal to `0.0` Prior to iOS 17, macOS 14, tvOS 17, and watchOS 10, the `default` animation is [`easeInOut`](/documentation/SwiftUI/Animation/easeInOut). The global function [`withAnimation(_:_:)`](/documentation/SwiftUI/withAnimation(_:_:)) uses the default animation if you don’t provide one. For instance, the following code listing shows an example of using the `default` animation to flip the text “Hello” each time someone clicks the Animate button. ``` struct ContentView: View { @State private var degrees = Double.zero var body: some View { VStack { Spacer() Text("Hello") .font(.largeTitle) .rotation3DEffect(.degrees(degrees), axis: (x: 0, y: 1, z: 0)) Spacer() Button("Animate") { withAnimation { degrees = (degrees == .zero) ? 180 : .zero } } } } } ```  To use the `default` animation when adding the [`animation(_:value:)`](/documentation/SwiftUI/View/animation(_:value:)) view modifier, specify it explicitly as the animation type. For instance, the following code shows an example of the `default` animation to spin the text “Hello” each time someone clicks the Animate button. ``` struct ContentView: View { @State private var degrees = Double.zero var body: some View { VStack { Spacer() Text("Hello") .font(.largeTitle) .rotationEffect(.degrees(degrees)) .animation(.default, value: degrees) Spacer() Button("Animate") { degrees = (degrees == .zero) ? 360 : .zero } } } } ```  A `default` animation instance is only equal to other `default` animation instances (using `==`), and not equal to other animation instances even when the animations are identical. For example, if you create an animation using the [`spring(response:dampingFraction:blendDuration:)`](/documentation/SwiftUI/Animation/spring(response:dampingFraction:blendDuration:)) modifier with the same parameter values that `default` uses, the animation isn’t equal to `default`. This behavior lets you differentiate between animations that you intentionally choose and those that use the `default` animation. --- Copyright © 2026 Apple Inc.
