I have a macCatalyst app that works perfectly on macOS 10.14, however on upgrading to macOS 11 (Big Sur) both I and my users are complaining that the app crashes on launch. I get an error message "Parameter was not of class UIScene" - do macCatalyst apps now require the use of scenes?
On further inspection, I see the following:

libc++abi.dylib: terminating with uncaught exception of type NSException
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Parameter was not of class UIScene.'
terminating with uncaught exception of type NSException
In a catalyst Swift project a UIViewController subclass creates a TouchBar like this:
override func makeTouchBar() -> NSTouchBar? {
let touchBar = NSTouchBar()
touchBar.delegate = self
touchBar.defaultItemIdentifiers = [<<some>>]
touchBar.customizationAllowedItemIdentifiers = [<<more>>]
touchBar.customizationIdentifier = "com.me.myapp.touchbar"
return touchBar
}
The default items show up on the TouchBar, but there is no menu item to customize them.
Reading the TouchBar documentation there are two options:
1: NSApplication
The Customization Menu Item
A user invokes the customization UI for a particular NSTouchBar object, when it is visible in the Touch Bar, by choosing the bar customization menu item. To enable this menu item you must explicitly opt-in, which you can do in the following ways:
If you want the system to automatically name, place, validate, and activate this menu item in your app’s menus, set the isAutomaticCustomizeTouchBarMenuItemEnabled property of your app object (of type NSApplication) to true.
To explicitly place the customization menu item in one of your app’s menus, employ the toggleTouchBarCustomizationPalette(_:) method of your app object. When you do this, the system still names and validates the menu item, and hides it on systems that do not have a Touch Bar.
Trying to do either of those yields a 'NSApplication' is unavailable in Mac Catalyst error.
So after some googling around I found this:
NSClassFromString("NSApplication")?.setValue(true, forKeyPath: "sharedApplication.automaticCustomizeTouchBarMenuItemEnabled")
print(NSClassFromString("NSApplication")?.value(forKeyPath: "sharedApplication.isAutomaticCustomizeTouchBarMenuItemEnabled"))
This compiles and executes fine. It even prints out Optional(1) where there was an Optional(0) before. But the menu item still is not there. I tried this at the point where I generate the TouchBar, where I generate the Menu, and in func application(_, didFinishLaunchingWithOptions), but to no avail.
I cannot get the second one to not give me an error.
2: TouchBar
Curiously the NSTouchBar has the same property, but running
NSTouchBar.isAutomaticCustomizeTouchBarMenuItemEnabled = true
at any point (which compiles, too) yields no difference.
Question
Is this a missing feature or is there a way to achieve it. And if so: how?
Edit
I am customizing the menu bar. Due to an error, setting the same shortcut for two options, causes the following output in Xcode:

But then the customize TouchBar action shows up in the menu (all my custom ones are gone), the ❗MISSING LABEL❗ issue is easily fixed.
So I wondered whether it was my menu customization code causing the error, but uncommenting the entire override func buildMenu(with builder: UIMenuBuilder) in my AppDelegate does not cause the customization menu to appear – only the shortcut collision does.
In my Swift Catalyst app (macOS 10.15.3, Xcode 11.3.1), I am able to call
NSTouchBar.isAutomaticCustomizeTouchBarMenuItemEnabled = true
in my override func makeTouchBar() method, and the "Customize Touch Bar..." menu item appears in the "View" menu tab. For the missing labels, the following works:
func touchBar(_ touchBar: NSTouchBar, makeItemForIdentifier identifier: NSTouchBarItem.Identifier) -> NSTouchBarItem? {
if identifier == yourIdentifier {
let item = NSPickerTouchBarItem(...)
item.customizationLabel = "View Segmented Control"
return item
}
return nil
}
I'm trying to use the NSSavePanel and added this line to my code.
let test = NSSavePanel()
Everytime this code is called the this error appears.
I'm not quite sure what is happening here because I'm only creating a new object.
Any help appreciated.
Thanks!

Your File Access permissions for the User Selected File type are probably still set to the default Read Only value
Navigate to the 'Capabilities' tab for your target
Set the User Selected File permission to Read/Write
Run your app (the bridge absent error should be gone)
I have built a document based app in swift and then I added a NSCollectionView to it with an add button next to it. The button would call a NSOpenPanel and then the icon of the item chosen should appear in the collection view. However, when I click the 'open' button in the NSOpenPanel, the following were printed to the console:

I think that the code that the problem is in should be in this segment:
extension Document : AddAttachmentDelegate {
internal func addFile() {
let panel = NSOpenPanel()
panel.allowsMultipleSelection = false
panel.canChooseDirectories = false
panel.canChooseFiles = true
panel.begin { (result) -> Void in
if result == NSModalResponseOK, let resultURL = panel.urls.first {
do {
try self.addAttachmentAtURL(url: resultURL)
self.attachmentsList?.reloadData()
} catch let error as NSError {
if let window = self.windowForSheet {
NSApp.presentError(error, modalFor: window, delegate: nil, didPresent: nil, contextInfo: nil)
} else {
NSApp.presentError(error)
}
}
}
}
}
}
I have no idea what is going on. Hope you can help.
EDIT: attachmentsList is connected by the following:
#IBOutlet weak var attachmentsList: NSCollectionView!
I am following the pattern used in the the example here :
https://github.com/lucasderraugh/AppleProg-Cocoa-Tutorials/blob/master/Lesson%2066/Lesson%2066/AppDelegate.swift
My VC (subclass of NSViewController) looks like this :
import Cocoa
class SecondViewController: NSViewController {
var leftView = ColorView()
var rightView = ColorView()
#IBOutlet weak var nameTextField: NSTextField!
override func viewDidLoad() {
super.viewDidLoad()
// Do view setup here.
}
override func viewDidAppear() {
leftView.translatesAutoresizingMaskIntoConstraints = false
rightView.translatesAutoresizingMaskIntoConstraints = false
let leftConstraints:[NSLayoutConstraint] = [
leftView.widthAnchor.constraintEqualToAnchor(self.view.topAnchor),
leftView.leftAnchor.constraintEqualToAnchor(self.view.leftAnchor),
leftView.widthAnchor.constraintEqualToConstant(100),
leftView.heightAnchor.constraintEqualToConstant(100)
]
self.view.addSubview(leftView)
NSLayoutConstraint.activateConstraints(leftConstraints)
}
override func prepareForSegue(segue: NSStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "SecondToFourthSegue" {
(segue.destinationController as! NSViewController).representedObject = nameTextField.stringValue
}
}
}
But I get the following error at runtime :
