How to create asymmetric transitions
Updated for Xcode 14.2
SwiftUI lets us specify one transition when adding a view and another when removing it, all done using the asymmetric() transition type.
For example, we can create a text view that uses asymmetric transitions so that it moves in from the leading edge when added and moves down to the bottom edge when being removed, 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(.asymmetric(insertion: .move(edge: .leading), removal: .move(edge: .bottom)))
}
}
}
}
