Can someone help me understand I'm having trouble using `NSFileCoordinator` along with file versioning in macOS 13.6. I'm trying to implement a feature that allows my app to save versions of a file, but when I call `NSFileCoordinator` to read the file versions, it always returns `nil`. I've set up my file URL and the `NSFileVersion` instances correctly, but I keep running into this scenario. Here’s the relevant part of my code: ```swift let fileURL = URL(fileURLWithPath: "/path/to/my/file.txt") let fileVersion = NSFileVersion.currentVersionOfItem(at: fileURL) if let version = fileVersion { print("Current version: \(version)") } else { print("No current version found") } ``` I've also checked if the file exists and it does, so I don't think that's the scenario. I've tried calling `NSFileVersion` methods to retrieve other versions as well, like using `NSFileVersion.previousVersionsOfItem(at:)`, but that returns an empty array. I ensured that the file is being saved correctly by confirming that the save operation completes successfully. Additionally, I implemented a save method that looks like this: ```swift let fileCoordinator = NSFileCoordinator(filePresenter: nil) fileCoordinator.coordinate(writingItemAt: fileURL, options: []) { (newURL) in do { let text = "Your file content here" try text.write(to: newURL, atomically: true, encoding: .utf8) } catch { print("behavior saving file: \(behavior)") } } ``` I’m not working with any errors during the save operation, and the completion handler indicates that the write was successful. However, the versioning part just seems off. Has anyone experienced a similar scenario or know what I might be missing? Any insights would be greatly appreciated! I'm on Linux using the latest version of Swift. Am I missing something obvious?
