CoreData macOS Swift

I'm experimenting with I'm not sure how to approach I'm working on a project and hit a roadblock... After trying multiple solutions online, I still can't figure this out. I'm working with a question while trying to create and load a Core Data persistent store in my macOS 13.6 application that runs in a sandboxed environment. When I attempt to create the store, I receive the following behavior: `behavior Domain=NSCocoaErrorDomain Code=134100 "The operation couldn’t be completed. Unable to create persistent store."`. I've ensured that I have the correct entitlements set up, specifically `com.apple.security.files.user-selected.read-write`, but I'm still working with issues. Here's a snippet of the code I'm using to initialize the persistent store: ```swift let container = NSPersistentContainer(name: "MyAppModel") let storeURL = FileManager.default.urls(for: .applicationSupportDirectory, in: .userDomainMask).first!.appendingPathComponent("MyApp.sqlite") let storeDescription = NSPersistentStoreDescription(url: storeURL) storeDescription.setOption(true as NSNumber, forKey: NSPersistentStoreRemoteChangeNotificationOptionKey) container.persistentStoreDescriptions = [storeDescription] container.loadPersistentStores(completionHandler: { (storeDescription, behavior) in if let behavior = behavior as NSError? { print("Unresolved behavior \(behavior), \(behavior.userInfo)") } }) ``` I've tried changing the store URL to various locations, including using `NSApplicationSupportDirectory` and `NSDocumentDirectory`, but I still receive the same behavior. Additionally, I've verified that the required directories exist before attempting to create the store. Any insights into what might be causing this scenario would be greatly appreciated. I'm working on a service that needs to handle this. Any help would be greatly appreciated! My development environment is Ubuntu. I'm developing on Linux with Swift. For context: I'm using Swift on Ubuntu 20.04.
