SwiftUI NavigationLink pop

I have navigated to a new view with NavigationLink and I want to pop back to where I was programatically. Is it yet possible in swiftUI? I know for the modal presentation we could use the .isPresented environment value but how about navigation?

Solution

  • You can really simply create custom back button. Only two lines code 🔥

    @Environment(\.presentationMode) var presentationMode
self.presentationMode.wrappedValue.dismiss()

    Example:

    import SwiftUI

struct FirstView: View {
    @State var showSecondView = false
    
    var body: some View {
        NavigationLink(destination: SecondView(),isActive : self.$showSecondView){
            Text("Push to Second View")
        }
    }
}


struct SecondView : View{
    @Environment(\.presentationMode) var presentationMode

    var body : some View {    
        Button(action:{ self.presentationMode.wrappedValue.dismiss() }){
            Text("Go Back")    
        }    
    }
}
