Updated for Xcode 14.2
When adding or removing a view, SwiftUI lets you combine transitions to make new animation styles using the combined(with:)
method.
For example, you can make a view move (one transition) and fade (a second transition) at the same time like this:
struct ContentView: View {
@State private var showDetails = false
var body: some View {
VStack {
Button("Press to show details") {
withAnimation {
showDetails.toggle()
}
}
if showDetails {
Text("Details go here.")
.transition(AnyTransition.opacity.combined(with: .slide))
}
}
}
}

To make combined transitions easier to use and re-use, you can create them as extensions on AnyTransition
. For example, we could define a custom moveAndScale
transition and try it out straight away:
extension AnyTransition {
static var moveAndScale: AnyTransition {
AnyTransition.move(edge: .bottom).combined(with: .scale)
}
}
struct ContentView: View {
@State private var showDetails = false
var body: some View {
VStack {
Button("Press to show details") {
withAnimation {
showDetails.toggle()
}
}
if showDetails {
Text("Details go here.")
.transition(.moveAndScale)
}
}
}
}
