How do I make a daily notification at 8 am? (Swift 3)

I ask you to ask this, but I tried it in different ways and none of them worked. I'm currently working on an app that gives you a little notification every day when you wake up with an interesting fact. It takes these facts from the array that is set. I tried to use UNNotificationCenter, UILocalNotification, etc., but I was unable to write this function. I would be glad if you could help me with this code!

So, at 8 am the application should

  • Call a function that gives it a new fact from an array and store it in UserDefaults lets you call it newFact()

  • Make a notification that appears at 8 a.m. every day, also if the phone is locked.

I would be very grateful if you could help me!

Use code below

You can call the function here



let fact = self.newfact()
UserDefaults.standard.set(fact,forKey: "fact")


var dateComp:NSDateComponents = NSDateComponents()
            dateComp.year = 2017;
            dateComp.month = 04;
            dateComp.day = 05;
            dateComp.hour = 08;
            dateComp.minute = 00;
            dateComp.timeZone = NSTimeZone.systemTimeZone()

        var calender:NSCalendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)!
        var date:NSDate = calender.dateFromComponents(dateComp)!

        var notification:UILocalNotification = UILocalNotification()
        notification.category = "Daily alarm "
        notification.alertBody = fact
        notification.fireDate = date
        notification.repeatInterval = NSCalendarUnit.CalendarUnitDay
