I just shared this Bug with Apple. I want to share with you.
Application Follow
1 - After the user logs on to the onBoardingView page, they are directed to ContentView with fullScreenCover.
2 - ContentView page contains objects in TabView that are repeated with ForEach. Clicking on these objects will take you to the DetailView page.
3 - However, Navigation repeats itself several times after clicking the object.
My English is bad. Sorry for this.

Project file is here
struct OnboardView: View {
@State var isLogin: Bool = false
var body: some View {
Button(action: {self.isLogin = true}) {
Text("Login")
}
.fullScreenCover(isPresented: self.$isLogin) {
ContentView()
}
}
}
struct ContentView: View {
@State var selected: String = ""
var items: [String] = ["1","2","3","4","5","6","7","8","9","10"]
var body: some View {
NavigationView {
TabView(selection: $selected) {
ForEach(items, id: \.self) { item in
NavigationLink(
destination: DetailView(),
label: {
Text(item)
.foregroundColor(.white)
.padding()
.background(Color.orange)
.cornerRadius(10)
})
}
}
.tabViewStyle(PageTabViewStyle(indexDisplayMode: .never))
.indexViewStyle(PageIndexViewStyle(backgroundDisplayMode: .always))
}
}
}
When working with ForEach
in SwiftUI, you have to be extra careful on the ids.
Try changing items to items.indices
instead:
ForEach(items.indices, id: \.self) { item in
NavigationLink(
destination: Text("Detail View"),
label: {
Text(items[item])
.foregroundColor(.white)
.padding()
.background(Color.orange)
.cornerRadius(10)
}
)
}
