SwiftUI - PresentationButton with modal that is full screen

Question

I am trying to implement a button that presents another scene with a \"Slide from Botton\" animation.

PresentationButton looked like a good candidate, so I gave it

Answer 1

Unfortunately, as of Beta 2 Beta 3, this is not possible in pure SwiftUI. You can see that Modal has no parameters for anything like UIModalPresentationStyle.fullScreen. Likewise for PresentationButton.

I suggest filing a radar.

The nearest you can currently do is something like:

    @State var showModal: Bool = false
    var body: some View {
        NavigationView {
            Button(action: {
                self.showModal = true
            }) {
                Text("Tap me!")
            }
        }
        .navigationBarTitle(Text("Navigation!"))
        .overlay(self.showModal ? Color.green : nil)
    }

Of course, from there you can add whatever transition you like in the overlay.
