SOLVED: How to quit .fullScreenCover ?

Forums > 100 Days of SwiftUI

So here is the situation. I have screen A,B and C. Screen A I have the code to open screen B as full screen

@State private var isPresented = false

    var body: some View {
        Button("Present!") {
            isPresented = true
        }
        .fullScreenCover(isPresented: $isPresented, content: B.init)
    }

Now I am in screen B where I can quit the screen and go back to screen A Or I have another button that takes me to screen C with the same code as above. Screen C has also option to quit and to open screen B again as full screen. After playing around a bit I noticed if you open screen B and C from each other a few times then when you click "quit" it wont exit both screens and take you to screen A but it will only go to the previous screen.

How can I program the button "quit" to exit both screen B and C and go back to A. I want this to happen no matter how many times I have opened screens B and C. Also for the button quit in B and C I used the

@Environment(\.dismiss) var dismiss

var body: some View {
      Button("Quit") {
            dismiss()
      }
}

Hi! I think the quickest way is to pass your initial isPresented as a binding to fullScreenCovers and if you created too many stacks and just want to jump back to initial screen you can change it false.

something like this:

struct ViewA: View {
    @State private var isRootPresented = false

    var body: some View {
        VStack(spacing: 20) {
            Text("This is A view")
            Button("Present B View") {
                isRootPresented = true
            }
            .fullScreenCover(isPresented: $isRootPresented) {
                ViewB(root: $isRootPresented)
            }
        }
    }
}

struct ViewB: View {
    @Environment(\.dismiss) var dismiss
    @State private var isPresented = false
    @Binding var root: Bool

    var body: some View {
        VStack(spacing: 20) {
            Text("This is B view")

            Button("Present C View") {
                isPresented = true
            }
            .fullScreenCover(isPresented: $isPresented) {
                ViewC(root: $root)
            }

            Button("Dismiss") {
                dismiss()
            }

            Button("Back to root") {
                root = false
            }
        }
    }
}

struct ViewC: View {
    @Environment(\.dismiss) var dismiss
    @State private var isPresented = false
    @Binding var root: Bool

    var body: some View {
        VStack(spacing: 20) {
            Text("This is C view")

            Button("Present B View") {
                isPresented = true
            }
            .fullScreenCover(isPresented: $isPresented) {
                ViewB(root: $root)
            }

            Button("Dismiss") {
                dismiss()
            }

            Button("Back to root") {
                root = false
            }
        }
    }
}
