Since transition affect many view here. You have to do the changes related to transition inside withAnimation(Animation.easeIn) { //here you can change the animation you want //state changes should write here } This link may helpfull [this video]

Hmm i feel you're missing the base of how swiftui works with views, and you patched some solutions from uikit to rotate things. I would suggest to watch some wwdc videos about swiftui or follow some base courses like the one that standford provide free on their youtube channel. Here a video that helps with your idea [this video] I added a solution that i come up on the fly but i would suggest to follow the Standford video because it provide a more complete solution where they use the AnimationModifier to handle the change from face up to flipped. To animate rotations you should use the .rotation3DEffect or .rotationEffect modifiers (it depends on the usecase). BTW here the base idea: flip to 90°

So this is my updated answer. I don't think there is a pretty way to do it so now I am doing it with a custom Button. import SwiftUI struct ContentView: View { @State var isShowing = false var body: some View { Text("Hello, world!") .padding() .onTapGesture(count: 1, perform: { withAnimation(.spring()) { self.isShowing.toggle() } }) .showModal(isShowing: self.$isShowing) } } extension View { func showModal(isShowing: Binding<Bool>) -> some View { ViewOverlay(isShowing: isShowing, presenting: { self }) } } struct ViewOverlay<Presenting>: View where Presenting: View { @Binding var isShowing: Bool let presenting: () -> Presenting @State var bottomState: CGFloat = 0 @State var isDragging = false
