我有这个应用程序，它将在iCloud.plist中创建文件备份。在我的测试设备（iPhone XR）中进行测试后，它可以顺利备份，但在使用不同的测试设备（如iPhone 6s plus、iPhone 5s和5 ）时。它不保存任何数据。它会自动跳转到警告控制器没有数据要保存。请参考下面的代码。请告诉我我错过了导致错误的代码部分。请帮助我解决这个问题将近 2 周，但我仍然没有找到任何解决方案。谢谢

 //the storage location of the plist you want to save
    let strLibraryPath = NSSearchPathForDirectoriesInDomains(.libraryDirectory, .userDomainMask, true)[0]
    let strPlistPath = "\(strLibraryPath)/\(S_DIRECTORY_NAME)/\(S_PLIST_NAME)"
    localURL = URL(fileURLWithPath: strPlistPath)

    //judge if there is plist to save
    let aFileManager = FileManager.default
    if !aFileManager.fileExists(atPath: strPlistPath) {
        let alertController = UIAlertController(title: "", message: "保存するデータがありません \n (No data to save)", preferredStyle: .alert)
        alertController.addAction(UIAlertAction(title: "OK", style: .default))
        self.present(alertController, animated: true, completion: nil)
    }

    else {

    blYesNoAlert = true
    let alert = UIAlertController(title: "Confirmation", message: "バックアップを作成しますか？\n (Do you want to make a backup?)", preferredStyle: UIAlertController.Style.alert)
    alert.addAction(UIAlertAction(title: "いいえ", style: UIAlertAction.Style.default, handler: { _ in
        //Cancel Action
    }))
    alert.addAction(UIAlertAction(title: "はい",
                                  style: UIAlertAction.Style.default,
                                  handler: {(_: UIAlertAction!) in

                                    Timer.scheduledTimer(timeInterval: 0.5, target: self, selector: #selector(self.backupData), userInfo: nil, repeats: false)

    }))
    self.present(alert, animated: true, completion: nil)
    }
}
