I’m trying to lock the rotation of my application using a bunch of methods that apple have now depreciated over the years and I’m at a loss.

There isn’t a SceneDelegate or AppDelegate in Xcode projects anymore using SwiftUI meaning that I can’t use any of the previous methods people came up with and programming the solution in SwiftUI: How do I lock a particular View in Portrait mode whilst allowing others to change orientation?. When I try to implement this solution into my program, Xcode returns a warning BUG IN CLIENT OF UIKIT: Setting UIDevice.orientation is not supported. Please use UIWindowScene.requestGeometryUpdate(_:)

Here is my current code

import SwiftUI

struct ContentView: View {
    @UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate

    
    var body: some View {
        ZStack {
            // rest of code is here
        }
    }.onAppear {
        UIDevice.current.setValue(UIInterfaceOrientation.portrait.rawValue, forKey: "orientation") // Forcing the rotation to portrait
        AppDelegate.orientationLock = .portrait // And making sure it stays that way
            
    }
        
}

class AppDelegate: NSObject, UIApplicationDelegate {
        
    static var orientationLock = UIInterfaceOrientationMask.all

    func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
        return AppDelegate.orientationLock
    }
}
