I want to setup a daily notification system for my app. It should notify the user twice a day, once at 8:00 AM (Hey there, your set of morning doses is ready. Wanna check it out?) and once at 7:00 PM (Ssup! Your evening Dose is waiting inside). I know that by doing this i'll run out of notifications in a month since there's a 64 notifications cap (for local notifications) but by then, the app will be live and i'll be done setting up remote notifications update.

I've looked at this question: How to schedule a same local notification in swift and the .Day is all good. I just need to know how to do it twice a day at those specified times;. Thanks in advance!

EDIT: how to set the specific time on the notification is part of the problem. The NSDate API is giving me funny time intervals (sinceNow/Since1973). I just want to set it to fire at 7 PM. :-/ Can't quite seem to do it with these NSDate apis unless I'm missing something.

Update for Swift 4.2

import UserNotifications

In AppDelegate confirm to UNUserNotificationCenterDelegate and in didFinishLaunchingWithOptions

let center = UNUserNotificationCenter.current() center.delegate = self; center.requestAuthorization(options: [UNAuthorizationOptions.alert, .badge, .sound]) { (granted, error) in if !granted { print("Permission Declined"); } } let content = UNMutableNotificationContent(); content.title = "HI"; content.body = "Your notification is here"; content.sound = UNNotificationSound.default; let gregorian = Calendar(identifier: Calendar.Identifier.gregorian); let now = Date(); var components = gregorian.dateComponents(in: .autoupdatingCurrent, from: now) let hours = [8,19]; for hour in hours { components.timeZone = TimeZone.current components.hour = hour; components.minute = 00; components.second = 00; let date = gregorian.date(from: components); let formatter = DateFormatter(); formatter.dateFormat = "MM-dd-yyyy HH:mm"; guard let dates = date else { return; } var fireDate: String? fireDate = formatter.string(from: dates); print("\(fireDate ?? "")"); // Just to Check let dailyTrigger = Calendar.current.dateComponents([.hour, .minute, .second], from: dates); let trigger = UNCalendarNotificationTrigger.init(dateMatching: dailyTrigger, repeats: true); let identifier = "Local Notification" let request = UNNotificationRequest(identifier: identifier, content: content, trigger: trigger) center.add(request) { (error) in if let error = error { print("Error \(error.localizedDescription)") } } }

hey! Thanks for the reply.... quick one... was hoping you'd tell me how to set the time to be 8: 00 AM / 7 PM because the NSDate API doesn't give me an option to set the time directly. only 'timeIntevalSinceNow/1970/reference' etc. Or am i supposed to use one of those? If so how would i go about it? Thanks
Thanks bunch mate. I guess the calendar is what i didn't know about. Looked around and a few people had the same problem. Apparently the calendar API isn't updated in the documentation. But I'll have to confirm that. Anyway, You're a hero mate!
right quick before we call it done, I need to set the repeat interval to .Day for the notifications to recur on a daily basis, yeah?
It supposed be. You can set a fire time, and see if it will show the notification for the second time.
