How to trigger a local notification at particular time daily in swift 3

Question

I am new to iOS development, but have created the app and I am trying to create a daily notification for specific time like (10AM). Now notification are coming too many if i se my mobile device time to 10AM. I want to trigger a local notification only once at given specific time that is at 10 AM , and I want to repeat this daily. What is the best method to repeat the notification daily ?

Here is my code

func fire(){
    let dateComp:NSDateComponents = NSDateComponents()
    dateComp.hour = 10
    dateComp.minute = 00
    dateComp.timeZone = NSTimeZone.systemTimeZone()
    let calender:NSCalendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierIndian)!
    let date:NSDate = calender.dateFromComponents(dateComp)!
    let localNotificationSilent = UILocalNotification()
    localNotificationSilent.fireDate = date
    localNotificationSilent.repeatInterval =  NSCalendarUnit.Day
    localNotificationSilent.alertBody = "Started!"
    localNotificationSilent.alertAction = "swipe to hear!"
    localNotificationSilent.timeZone = NSCalendar.currentCalendar().timeZone
   localNotificationSilent.category = "PLAY_CATEGORY"
   UIApplication.sharedApplication().scheduleLocalNotification(localNotificationSilent)    
}

Working in Swift 3, iOS 10:

UNUserNotificationCenter.current().requestAuthorization(
    options: [.alert, .sound, .badge], completionHandler: {userDidAllow, error in
    //if userDidAllow : do something if you want to 
})

//Set notification to trigger 11:30AM everyday
var dateComponents = DateComponents()
dateComponents.hour = 11
dateComponents.minute = 30
let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)

//Set your content
let content = UNMutableNotificationContent()
content.title = "Your notification title"
content.body = "Your notification body"

let request = UNNotificationRequest(
    identifier: "yourIdentifier", content: content, trigger: trigger
)
UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)

Hey, I am not able to fire notification at specific time. I did same code. — Abha, Oct 11 '17 at 05:21

your problem is fire date which is not proper

you can create fire date like this way

    let today = Date()
    let calendar = NSCalendar.current
    let components = calendar.dateComponents([.day, .month, .year], from: today)

    var dateComp:DateComponents = DateComponents()
    dateComp.day = components.day
    dateComp.month = components.month
    dateComp.year = components.year
    dateComp.hour = 10
    dateComp.minute = 00
    let date = calendar.date(from: dateComp)

if you want to verify fire date then you can check like this way

    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "dd MM yyyy hh:mm:ss"
    let fireDate = dateFormatter.string(from: date!)
    print("fireDate: \(fireDate)")

Now it's time to set fire date to local notification

localNotificationSilent.fireDate = date
// no need to set time zone Remove bellow line
localNotificationSilent.timeZone = NSCalendar.currentCalendar().timeZone

Notification code

    let localNotificationSilent = UILocalNotification()
    localNotificationSilent.fireDate = date
    localNotificationSilent.repeatInterval = .day
    localNotificationSilent.alertBody = "Started!"
    localNotificationSilent.alertAction = "swipe to hear!"
    localNotificationSilent.category = "PLAY_CATEGORY"
    UIApplication.shared.scheduleLocalNotification(localNotificationSilent)

I hope it will help you.
