navigationView中的SwiftUI自定义动画过渡？

struct ContentView: View {
    @State private var isShowingDetail = false
    
    var body: some View {
        NavigationView {
            VStack {
                Button("Show Detail") {
                    withAnimation {
                        isShowingDetail.toggle()
                    }
                }
                
                if isShowingDetail {
                    DetailView()
                        .transition(.customTransition)
                }
            }
        }
    }
}

struct DetailView: View {
    var body: some View {
        Text("Detail View")
            .font(.largeTitle)
            .foregroundColor(.blue)
    }
}

extension AnyTransition {
    static var customTransition: AnyTransition {
        let insertion = AnyTransition.move(edge: .trailing)
            .combined(with: .scale)
            .combined(with: .opacity)
        
        let removal = AnyTransition.move(edge: .leading)
            .combined(with: .scale)
            .combined(with: .opacity)
        
        return .asymmetric(insertion: insertion, removal: removal)
    }
}
