Hi, I am giving Mac Catalyst a try and Apple has provided a tutorial for that but it seems a bit buggy. In the tutorial https://developer.apple.com/tutorials/mac-catalyst/updating-the-app-icon there is the completed Catalyst xcode project (in the Complete folder). I downloaded and ran the completed project in Xcode Version 14.2, using my Mac to run it in simulation. The toolbar at the top of the window has the icons for edit and favorite but they appear to be greyed out and don't do anything when clicked. The selectors are set properly for their actions in the ToolBarDelegate file but nothing happens when I select a recipe, which it appears you have to do in order for those buttons to work, then try to click either one of those items Those buttons never appear to be enabled at all even though I have selected a recipe and the coding seems correct. I am confused as to why this doesn't work. The NSSharingServicePickerToolbarItem is enabled and seems to work. I didn't post any code since the project can be readily downloaded and viewed/run. Any help is much appreciated

Hi. I have a short program that adds two buttons in a single view and prints the screen bounds, but those bounds aren't right with iPhone 7Plus simulator after rotating device so the two button subviews aren't placed correctly. This issue does not seem to happen when using iPad simulators. I know I can just simply use the size input from viewWillTransition() function but that doesn't tell me why it isn't showing the correct screen bounds rectangle coordinates on just the iPhone simulator. For some reason it thinks device is in whatever mode it was in when I start up the app and rotate it. Like after I start up in Portrait and change to Landscape the code still prints "Device is in portrait mode" and prints the bounds as being in Landscape mode. I am using XCode 13.2.1 and iOS 15.2 for testing. All possible device orientations are in the info.plist for both iPhone and IPad. Here is the code I am testing with: import UIKit class TestViewController: UIViewController {          lazy var pickButton : UIButton = {         let button = UIButton(frame: CGRect(x: 0,                                             y: 0,                                             width: 100,                                             height: 100))         button.setTitle("Pick", for: .normal)         button.setTitleColor(.black, for: .normal)         //button.addTarget(self, action: #selector(showPicker), for: .touchUpInside)         return button     }()          lazy var resultsButton : UIButton = {         let button = UIButton(frame: CGRect(x: 0,                                             y: UIScreen.main.bounds.height - 100,                                             width: UIScreen.main.bounds.width,                                             height: 100))         button.setTitle("Show selected", for: .normal)         button.setTitleColor(.black, for: .normal)         //button.addTarget(self, action: #selector(showResults), for: .touchUpInside)         return button     }()     override func viewDidLoad() {         super.viewDidLoad()                  determineMyDeviceOrientation()                  /*let device = UIDevice.current         device.beginGeneratingDeviceOrientationNotifications()         let notificationCenter = NotificationCenter.default         notificationCenter.addObserver(self, selector: #selector(deviceOrientationChanged),             name: Notification.Name("UIDeviceOrientationDidChangeNotification"),             object: nil)*/                                    view.addSubview(resultsButton)         view.addSubview(pickButton)         pickButton.center = view.center     }          override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {                  print ("size \(size)")         print (UIScreen.main.bounds)                  determineMyDeviceOrientation()                  pickButton.center = CGPoint(x: UIScreen.main.bounds.width/2, y: UIScreen.main.bounds.height/2)         resultsButton.frame = CGRect(x: 0, y: UIScreen.main.bounds.height - 100, width: UIScreen.main.bounds.width, height: 100)                  //pickButton.center = CGPoint(x: size.width/2, y: size.height/2)         //resultsButton.frame = CGRect(x: 0, y: size.height - 100, width: size.width, height: 100)     }          func determineMyDeviceOrientation() {                      let i = UIApplication.shared.windows.first!.windowScene!.interfaceOrientation.isLandscape           print (i)                      if i {               print("Device is in landscape mode")           } else {               print("Device is in portrait mode")           }       }     @objc func deviceOrientationChanged() {         print("Orientation changed")         inspectDeviceOrientation()     }     func inspectDeviceOrientation() {         let orientation = UIDevice.current.orientation         switch UIDevice.current.orientation {         case .portrait:             print("portrait")         case .landscapeLeft:             print("landscapeLeft")         case .landscapeRight:             print("landscapeRight")         case .portraitUpsideDown:             print("portraitUpsideDown")         case .faceUp:             print("faceUp")         case .faceDown:             print("faceDown")         default: // .unknown             print("unknown")         }         if orientation.isPortrait { print("isPortrait") }         if orientation.isLandscape { print("isLandscape") }         if orientation.isFlat { print("isFlat") }     } }
