I figured it out. The url is scoped and so I had to direct it to start using the scoped url. like so,         guard let selectedURL = try? result.get() else {return}         if selectedURL.startAccessingSecurityScopedResource() {             do {                 if let selectedData = try? Data(contentsOf: selectedURL) {                     self.coverData = selectedData                     if let uiImage = UIImage(data: selectedData) {                         self.coverImage = Image(uiImage: uiImage)                     }                 }             } catch {                 print(error.localizedDescription)             }         }         selectedURL.stopAccessingSecurityScopedResource()     }

in the init use themodelValue = State(initialValue value: newValue)

I am sorry i took so long to respond. i was not aware that this forum did not email me when i have a response like reddit does. And i stopped checking on it every day like i did when i first posted it. I tried your method and it did improve it a little but it was still not what i wanted. When i clicked on a link in the second navigation view it would cover that navigation list with the detail view. I decided to scrap the methodology that i was trying for and to go with a segmented button on the toolbar for tabs on catalyst and then tabview on the ios code. Thanks for all your help.

ok i think i solved that problem, i put the code in the scenedelegate not the app delegate and i dont get the error anymore. problem is that now i do not know how to actually implement a sidebar in a catalyst master/detail view using the uisplitviewcontroller? I could not find any tutorial on this and the apple article stopped at the .sidebar setting. So how do i implement a master/detail with sidebar in swiftui for catalyst?

If I did that I couldn’t use the navigation link to the Accountdetailview

that still turns the navigation links into buttons and not text.

davea,if i change the lists to vstacks, it fixes it but then it changes the links to buttons instead of text. I cant even style the buttons with plainbuttonstyle because its a text that i used.

Claude31 i tried that it does not work as expected. It puts this weird line in the middle and the bottom list still hugs the top of the list i want it to hug the bottom like on the app store app. Also for some reason this method will not work in the preview.import SwiftUI struct ContentView: View { var body: some View { NavigationView { VStack { List { NavigationLink("Item #1", destination: Text("Item1").frame(maxWidth: .infinity, maxHeight: .infinity)) NavigationLink("Item #2", destination: Text("Item2").frame(maxWidth: .infinity, maxHeight: .infinity)) } Spacer() List { NavigationLink("Item #3", destination: Text("Item3").frame(maxWidth: .infinity, maxHeight: .infinity)) } }.frame(width: 100) } } }
