How to dismiss SwiftUI modal view

Very often we present a SwiftUI view modally using sheet modifier, or by pushing it onto the navigation stack. In order to dismiss it, you can use presentationMode environment value:

struct SettingsScreen: View {
    @Environment(\.presentationMode) var presentationMode
    
    var body: some View {
        NavigationView {
            Text("Hello, World!")
                .toolbar {
                    ToolbarItem(placement: .navigationBarTrailing) {
                        Button("Dismiss") {
                            presentationMode.wrappedValue.dismiss()
                        }
                    }
                }
        }
    }
}

The benefit of this approach is that it works both for navigation stacks and for modal sheets. It also works when we present SwiftUI view embedded into a UIHostingController from UIKit context.

The environment value presentationMode works from iOS 12.0, but since iOS 15.0 we have a new, direct API to dismiss views which is dismiss environment value:

@available(iOS 15.0, *)
struct SettingsScreen: View {
    @Environment(\.dismiss) var dismiss
    
    var body: some View {
        NavigationView {
            Text("Hello, World!")
                .toolbar {
                    ToolbarItem(placement: .navigationBarTrailing) {
                        Button("Dismiss") {
                            dismiss()
                        }
                    }
                }
        }
    }
}
