I have a bug on SwiftUI, when I rotate my device the modal don't longer dismiss, the problem here is that only happen on the device on the simulator works well also on my iPad.

import SwiftUI

struct modalView: View {
    @Environment(\.presentationMode) var presentationMode

    var body: some View {
        Button(action:{
            self.presentationMode.wrappedValue.dismiss()
        }){
            Text("close")
        }
    }
}

struct ContentView: View {
    @State var showModal = false
    var body: some View {
        Button(action: {
            showModal.toggle()
        }){
            Text("modal")
        }
        .sheet(isPresented: self.$showModal, content: {
            modalView()
        })
    }
}

Try to use something like this:

struct ContentView: View {

  @State private var showModal = false

  // If you are getting the "can only present once" issue, add this here.
  // Fixes the problem, but not sure why; feel free to edit/explain below.
  @Environment(\.presentationMode) var presentationMode


  var body: some View {
    Button(action: {
        self.showModal = true
    }) {
        Text("Show modal")
    }.sheet(isPresented: self.$showModal) {
        ModalView()
    }
  }
}


struct ModalView: View {

  @Environment(\.presentationMode) private var presentationMode

  var body: some View {
    Group {
      Text("Modal view")
      Button(action: {
         self.presentationMode.wrappedValue.dismiss()
      }) {
        Text("Dismiss")
      }
    }
  }
}

I Found the problem, I was using a condition to show two different navigations views, that break the dismiss modal

if self.sizeClass == .compact{
NavigationViewForiPhone()
} else {
NavigationViewForiPad()
}

looks like thats the problem cuz my view is reload
