SwiftUI-Presentation.swift

import PlaygroundSupport
import SwiftUI

struct DetailView: View {
  @Environment(\.isPresented) var isPresented: Binding<Bool>?
  @State var count = 0

  var body: some View {
    VStack(spacing: 20) {
      Text("Count: \(count)")

      Button(action: add) {
        Text("Add")
      }

      if isPresented != nil {
        Button(action: dismiss) {
          Text("Dismiss")
        }
      }
    }
  }

  func add() {
    count += 1
  }

  func dismiss() {
    isPresented?.value = false
  }
}

struct ContentView: View {
  var body: some View {
    NavigationView {
      VStack(spacing: 20) {
        NavigationLink(destination: DetailView()) {
          Text("Push")
        }
        PresentationLink(destination: DetailView()) {
          Text("Present")
        }
      }
    }
  }
}

PlaygroundPage.current.liveView = UIHostingController(rootView: ContentView())

It works nicely, thank you.

Interestingly, if I put the PresentationLink in .navigationBarItems, it brings up the DetailView just once, after Dismiss, the link doesn't work any more. Any idea why?

@Laszlo75 I have no idea.

I found it's a beta bug when I learn https://designcode.io/swiftui-modal-presentation

Second Tap Issue
In the beta, when clicked a second time, it won't present the modal again.

Does this code still work!?

getting issue with:

@Environment(.isPresented) var isPresented: Binding?
