下面是我的viewController代码

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // 1. REQUEST PERMISSION
        UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
            if granted {
                print("Notification access granted")
            } else {
                print(error?.localizedDescription as Any)
            }
        }

    }

    @IBAction func notoify(_ sender: UIButton) {
        scheduleNotification(inSeconds: 5, completion: {
            success in if success {
                print("Ok")
            } else {
                print("Error scheduled notification")
            }

        })
    }

    func scheduleNotification(inSeconds: TimeInterval, completion: @escaping (_ Success: Bool) -> ()){

        let notification = UNMutableNotificationContent()
        notification.title =  "Notification"
        notification.subtitle =  "These are great"
        notification.body = "Test test test test test test test test"

        let notificationTrigger = UNTimeIntervalNotificationTrigger(timeInterval: inSeconds, repeats: false)

        let notificationRequest = UNNotificationRequest(identifier: "myNotification", content: notification, trigger: notificationTrigger)

        UNUserNotificationCenter.current().add(notificationRequest, withCompletionHandler: {
            error in if error != nil {
                print(error as Any)
                completion(false)
            }
            else {
                completion(true)
            }
        })

    }

}

我最近在将我的xcode更新到11.4.1版本后遇到了这个问题。我解决这个问题的唯一方法是完全卸载xcode并重新安装它。重新安装完成后，我再也没有看到这个错误，我所有的Flutter和其他移动项目都可以正常工作，没有任何问题。

在经历了完全相同的问题后，完全卸载XCode并重新安装对我来说也是有效的。
