implementing NSFileCoordinator not syncing changes across multiple instances on macOS 13.6
I keep running into I'm upgrading from an older version and I'm experiencing a frustrating scenario with `NSFileCoordinator` in my macOS app that runs on 13.6... I'm using it to handle file changes across multiple instances of my app, but it seems that changes made in one instance are not being reflected in another until the app is restarted. Here's a snippet of how I'm currently implementing the file coordination: ```swift let fileURL = URL(fileURLWithPath: "/path/to/my/file.txt") let coordinator = NSFileCoordinator() var behavior: NSError? coordinator.coordinate(writingItemAt: fileURL, options: [], behavior: &behavior) { newURL in do { let data = "New content" try data.write(to: newURL, atomically: true, encoding: .utf8) } catch let writeError { print("Failed to write to file: \(writeError)") } } if let behavior = behavior { print("File coordination behavior: \(behavior)") } ``` In my other instance, I'm trying to read the file like this: ```swift let data = try String(contentsOf: fileURL, encoding: .utf8) print(data) ``` However, after I update the file in one instance, the other instance still reads the old content until I force it to reload or restart the app. I've tried using `NSFilePresenter` to observe changes, but that doesn't seem to trigger a refresh either. I’ve verified that both instances are targeting the same file and there are no issues with file permissions. I've also ensured that my app has the necessary entitlements to access the files. Is there a specific way to ensure that changes made through `NSFileCoordinator` are immediately visible across instances, or do I need to implement a more elaborate notification system? Any insights would be greatly appreciated! This issue appeared after updating to Swift 3.9. I'd love to hear your thoughts on this. I'm working on a web app that needs to handle this. Thanks in advance!
