I am writing an app that needs to have multiple documents in one window (as was asked about here. So I can't just make it a "document-based application", but I am still trying to use the document architecture to save the individual files.
What I'm specifically trying to do is close all open documents, and preferably save them if they have been modified. It seems like the best way to do this is to call the closeAllDocumentsWithDelegate method of the shared document controller. But I don't know what parameters to pass it. The docs say it is:
func closeAllDocumentsWithDelegate(_ delegate: AnyObject?,
didCloseAllSelector didCloseAllSelector: Selector,
contextInfo contextInfo: UnsafeMutablePointer)
They don't say what these mean, though. What delegate, selector and contextInfo should I be calling? I can't find examples of this method being used successfully. I tried seeing if I could get away with self and nil just to get it to compile:
SharedDocumentController.sharedDocumentController().closeAllDocumentsWithDelegate(self, didCloseAllSelector: nil, contextInfo: nil)
But then I get the error "Thread 1: EXC_BAD_ACCESS (code=1, address=0x0)", which I'm told is a null pointer exception. So at least one of those nils is a no-go, probably because of a forced unwrap somewhere. Fine, but what would I put there instead?
EDIT: as requested below, I am attaching a pic of the stacktrace:
And of the console:

libc++abi.dylib: terminating with uncaught exception of type NSException
This method simply executes -canCloseDocumentWithDelegate:shouldCloseSelector:contextInfo: for all open windows. So look at its documentation. (Linked above.)
The short form: You can pass a delegate object, which will be informed about the close request via the method that responds to the selector, you passed.
So let's say, the object that should be informed is the app delegate, then you pass this as delegate parameter and write a method in the app delegate, whose selector you pass as selector parameter. In Swift you must decorate that method (Swift: function) with #objc.
The contextInfo is any user-definable data to pass or not. It is simply passed through. It is a "communication channel" from caller in your code to the delegate method, i. e. signaling the reason for the close. You can pass nil for it.
Even I did not test it, but typically you can pass nil for delegate, too. In such a case you should be able to pass NULL (it is no type) for the selector. Just try it. Then you do not need an empty method.

I'm trying to get a particle effect across my whole background in storyboards using a SpriteKit view that I added but this keeps making my app crash. I tried to add it by code but this aswell crashed my app and I don't really know what to make out of the error message as I can't find much about it on the internet...
I linked my SpriteKit view with my 'MyParticle.sks' file

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:

You need to import CallKit Framework in your project Framework,Libraries, and Embeded Content section.
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!
