Help with presenting SwiftUI view on iMessage Extension using hosting controller on iOS 16
Hello, I am a new developer and it is my first time trying to build an iMessage Extension app. I am having an issue with presenting a SwiftUI view using a hosting controller in iOS 16. My code works on earlier OS versions, but for some reason when I updated to iOS 16 the view constraints seem off. I am running the app on an iPhone 13 on iOS 16.03 and what I encounter is the following: When I open the app the view appears all the way at the top of the screen past the safe area. I was able to replicate the issue using the IceCreamBuilderMessagesExtension project in apple docs (https://developer.apple.com/documentation/messages/icecreambuilder_building_an_imessage_extension). I got rid of most of the code in the IceCreamBuilder project to try and isolate just the issue with presenting a SwiftUI view. Here is my code in the IceCreamBuilder project: /* The root view controller shown by the Messages app. */ import UIKit import Messages import SwiftUI class MessagesViewController: MSMessagesAppViewController {   // MARK: Properties       override func willBecomeActive(with conversation: MSConversation) {     super.willBecomeActive(with: conversation)           // Present the view controller appropriate for the conversation and presentation style.     presentViewController(for: conversation, with: presentationStyle)   }       // MARK: MSMessagesAppViewController overrides       override func willTransition(to presentationStyle: MSMessagesAppPresentationStyle) {     super.willTransition(to: presentationStyle)           // Hide child view controllers during the transition.     removeAllChildViewControllers()   }       override func didTransition(to presentationStyle: MSMessagesAppPresentationStyle) {     super.didTransition(to: presentationStyle)           // Present the view controller appropriate for the conversation and presentation style.     guard let conversation = activeConversation else { fatalError("Expected an active converstation") }     presentViewController(for: conversation, with: presentationStyle)   }       // MARK: Child view controller presentation       /// - Tag: PresentViewController   private func presentViewController(for conversation: MSConversation, with presentationStyle: MSMessagesAppPresentationStyle) {     // Remove any child view controllers that have been presented.     removeAllChildViewControllers()           let controller = UIHostingController(rootView: TestView())     addChild(controller)     controller.view.frame = view.bounds     controller.view.translatesAutoresizingMaskIntoConstraints = false     view.addSubview(controller.view)           NSLayoutConstraint.activate([       controller.view.leftAnchor.constraint(equalTo: view.leftAnchor),       controller.view.rightAnchor.constraint(equalTo: view.rightAnchor),       controller.view.topAnchor.constraint(equalTo: view.topAnchor),       controller.view.bottomAnchor.constraint(equalTo: view.bottomAnchor)       ])           controller.didMove(toParent: self)   }           // MARK: Convenience       private func removeAllChildViewControllers() {     for child in children {       child.willMove(toParent: nil)       child.view.removeFromSuperview()       child.removeFromParent()     }   }      } // TestView.swift // IceCreamBuilderMessagesExtension import SwiftUI struct TestView: View {   var body: some View {     VStack {       Text("Test")       Text("Test")       Text("Test")       Text("Test")       Text("Test")     }   } } Any help/insight is very much welcomed, Thank you
