Question

As long as the datePicker selection is closed, everything is fine. When the calendar sheet is left open, and the dismiss (.onTapGesture) is pressed, the onDismiss closure is done, but the screen will not return. Tried setting the isPresenting to false in the didDismiss() with the same results.

getting this error

     struct FullScreenCoverPresentedOnDismiss: View {
     @State private var isPresenting = false
     @State private var birthDate = Date()
     var body: some View {
         Button("Present Full-Screen Cover") {
             isPresenting.toggle()
         }
         .fullScreenCover(isPresented: $isPresenting,
                          onDismiss: didDismiss) {
             VStack {
                 DatePicker(selection: $birthDate, in: ...Date(), displayedComponents: .date) {
                     Text("Select a date")
                 }
                 Text("A full-screen modal view.")
                     .font(.title)
                 Text("Tap to Dismiss")
                     .onTapGesture {
                                          isPresenting.toggle()
                                      }
             }

             .foregroundColor(.white)
             .frame(maxWidth: .infinity,
                    maxHeight: .infinity)
             .background(Color.blue)
             .ignoresSafeArea(edges: .all)
         }
     }

     func didDismiss() {
         print("didDismiss")
     }
 }

我发现的唯一工作是总结你想在被解雇日期之后提出的事情。

// Adjust the delay as needed (I ve used 0.25 secs with success) 
DispatchQueue.main.asyncAfter(deadline: .now() + delayInSeconds) { 
    showingConfirmationDialog = true
}
