How to resolve many issues.

If you edit and relaunch your app your Alarm Clock will break. Just Delete UIApplication.shared.scheduledLocalNotifications = nil in MainAlarmViewController.swift.

To resolve trouble with getting notifications in other VC and getting notifications when app closed make this: ` func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { alarmScheduler.setupNotificationSettings() window?.tintColor = UIColor.red

    let notificationSettings = UIUserNotificationSettings(types: .alert, categories: nil)
    UIApplication.shared.registerUserNotificationSettings(notificationSettings)

    if let notification = launchOptions?[UIApplicationLaunchOptionsKey.localNotification] as? UILocalNotification {
        if let userInfo = notification.userInfo {
            let index = userInfo["index"] as! Int
            let storyboard = UIStoryboard(name: "Main", bundle: nil)
            let mainVC = storyboard.instantiateViewController(withIdentifier: "Alarm") as! MainAlarmViewController
            if mainVC.alarmModel.alarms[index].repeatWeekdays.isEmpty {
                mainVC.alarmModel.alarms[index].enabled = false
            }
        }
        DispatchQueue.main.async {

            let alertController = UIAlertController(title: "Alarm", message: nil, preferredStyle: .alert)
            alertController.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
            self.window?.rootViewController?.present(alertController, animated: true, completion: nil)
        }
    }

    return true
}

//receive local notification when app in foreground
func application(_ application: UIApplication, didReceive notification: UILocalNotification) {

    //show an alert window
    let storageController = UIAlertController(title: "Alarm", message: nil, preferredStyle: .alert)
    var isSnooze: Bool = false
    var soundName: String = ""
    var index: Int = -1
    if let userInfo = notification.userInfo {
        isSnooze = userInfo["snooze"] as! Bool
        soundName = userInfo["soundName"] as! String
        index = userInfo["index"] as! Int
    }

    playSound(soundName)
    //schedule notification for snooze
    if isSnooze {
        alarmScheduler.setNotificationForSnooze(snoozeMinute: 9, soundName: soundName, index: index)
        let snoozeOption = UIAlertAction(title: "Snooze", style: .default) {
            (action:UIAlertAction)->Void in self.audioPlayer?.stop()
        }
        storageController.addAction(snoozeOption)
    }
    let stopOption = UIAlertAction(title: "OK", style: .default) {
        (action:UIAlertAction)->Void in self.audioPlayer?.stop()
        //change UI
        if let mainVC = self.window?.visibleViewController as? MainAlarmViewController {
            if mainVC.alarmModel.alarms[index].repeatWeekdays.isEmpty {
                mainVC.alarmModel.alarms[index].enabled = false
            }
            let cells = mainVC.tableView.visibleCells
            for cell in cells {
                if cell.tag == index {
                    let sw = cell.accessoryView as! UISwitch
                    if mainVC.alarmModel.alarms[index].repeatWeekdays.isEmpty {
                        sw.setOn(false, animated: false)
                        cell.backgroundColor = UIColor.groupTableViewBackground
                        cell.textLabel?.alpha = 0.5
                        cell.detailTextLabel?.alpha = 0.5
                    }
                }
            }
        } else {
            let storyboard = UIStoryboard(name: "Main", bundle: nil)
            let mainVC = storyboard.instantiateViewController(withIdentifier: "Alarm") as! MainAlarmViewController
            if mainVC.alarmModel.alarms[index].repeatWeekdays.isEmpty {
                mainVC.alarmModel.alarms[index].enabled = false
            }
        }
    }

    storageController.addAction(stopOption)
    window?.visibleViewController?.navigationController?.present(storageController, animated: true, completion: nil)
}`

Make Extension.swift `import Foundation

import UIKit

public extension UIWindow { public var visibleViewController: UIViewController? { return UIWindow.getVisibleViewControllerFrom(vc: self.rootViewController) }

public static func getVisibleViewControllerFrom(vc: UIViewController?) -> UIViewController? {
    if let nc = vc as? UINavigationController {
        return UIWindow.getVisibleViewControllerFrom(vc: nc.visibleViewController)
    } else if let tc = vc as? UITabBarController {
        return UIWindow.getVisibleViewControllerFrom(vc: tc.selectedViewController)
    } else {
        if let pvc = vc?.presentedViewController {
            return UIWindow.getVisibleViewControllerFrom(vc: pvc)
        } else {
            return vc
        }
    }
}

} `

That's all
