Любая информация об ошибке MCMErrorDomain 44?

Question

Я сталкиваюсь с "MCMErrorDomain error 44" примерно в 50% времени в app.launch () при загрузке контейнера в мое приложение. Я понятия не имею, в чем причина, и я не могу найти информацию об этой ошибке.

Это код, который я использую для загрузки контейнера в приложение.

extension AppDelegate {
    func loadAppData(appDataPath: String) {
        let loaderUrl = URL(fileURLWithPath: #file)
        let bundleUrl = URL(fileURLWithPath: appDataPath, relativeTo: loaderUrl).appendingPathExtension("xcappdata")
        let contentsURL = bundleUrl.appendingPathComponent("AppData")
        let fileManager = FileManager.default

        let enumerator = fileManager.enumerator(at: contentsURL,
                                                includingPropertiesForKeys: [.isDirectoryKey],
                                                options: [],
                                                //swiftlint:disable:next force_unwrapping
                                                errorHandler: nil)!
        //swiftlint:disable:next force_unwrapping
        let destinationRoot = fileManager.urls(for: .libraryDirectory, in: .userDomainMask).last!.deletingLastPathComponent()
        let test =  fileManager.enumerator(at: destinationRoot,
                                           includingPropertiesForKeys: [.isDirectoryKey],
                                           options: [],
                                           //swiftlint:disable:next force_unwrapping
                                           errorHandler: nil)!

        while let lol = test.nextObject() as? URL {
            do {
                try fileManager.removeItem(at: lol)
            } catch {
                print("✌️ \(error)")
            }
        }

        print("✌️ \(destinationRoot)")
        let sourceRoot = contentsURL.standardizedFileURL.path
        while let sourceUrl = enumerator.nextObject() as? URL {
            guard let resourceValues = try? sourceUrl.resourceValues(forKeys: [.isDirectoryKey]),
                let isDirectory = resourceValues.isDirectory,
                !isDirectory else {
                    continue
            }
            let path = sourceUrl.standardizedFileURL.path.replacingOccurrences(of: sourceRoot, with: "")
            let destinationURL = destinationRoot.appendingPathComponent(path)
            do {
                try fileManager.createDirectory(at: destinationURL.deletingLastPathComponent(),
                                                withIntermediateDirectories: true,
                                                attributes: nil)

                try fileManager.copyItem(at: sourceUrl,
                                         to: destinationURL)
            } catch {
                print("✌️ \(error)")
                do {
                    _ = try fileManager.replaceItemAt(destinationURL, withItemAt: sourceUrl)
                } catch {
                    print("✌️ \(error)")
                }
            }
        }
        print("done")
    }
