SwiftUI: Clear Modal state or Reinitialize

Question

I have a SwiftUI modal that I would like to either clear the state of or reinitialize. Reinitalizing would be preferred considering the fact that this modal can open other modal

Update September 11th: This appears to be fixed in iOS 13 GM.

I've been struggling with the same thing and I would like to think that this is a bug that will be resolve by September, I've already filed it on Feedback Assistant, make sure to do the same!

For now though you can just create a new UIHostingController that wraps the SwiftUI View that you want to show modally. I know it looks really hacky but at least it works:

import SwiftUI

struct OtherView: View {
    @State var otherViewState: String = ""

    var body: some View {
        TextField($otherViewState, placeholder: Text("Demo Text Input"))
    }
}

struct Demo: View {
    var body: some View {
        Button("Toggle Modal") {
            self.showModal()
        }
    }

    func showModal() {
        let window = UIApplication.shared.windows.first
        window?.rootViewController?.present(UIHostingController(rootView: OtherView()), animated: true)
    }
}

You might want to improve how you get the window, specially if you support multiple windows but I think you get the idea.
