SwiftUI dismiss modal

Question

Since SwiftUI is declarative there is no dismiss methode. How can is add a dismiss/close button to the DetailView?

Answer 1

Use Environment variable at PresentationMode. This GitHub link will maybe help you to solve the problem https://github.com/MannaICT13/Sheet-in-SwiftUI

This is simple solution:

struct ContentView2 : View {

    @Environment (\.presentationMode) var presentationMode

    var body : some View {
        VStack {
            Text("This is ContentView2")
            Button(action: {
                self.presentationMode.wrappedValue.dismiss()
            }, label: {
                Text("Back")    
            })    
        }
    }
}


struct ContentView: View {

    @State var isShowingSheet : Bool = false

    var body: some View {
        Button(action: {
            self.isShowingSheet.toggle()
        }, label: {
            Text("Click Here")
        }).sheet(isPresented: $isShowingSheet, content: {  
            ContentView2()
        })
    }
}
