There are two types of triggers in User Notifications framework:

1. UNTimeIntervalNotificationTrigger - Used for creating a notification with a set interval time:

   Fire in 30 minutes (60 seconds times 30) ,

   let trigger = UNTimeIntervalNotificationTrigger(timeInterval: (30*60), repeats: false)
   

2. UNCalendarNotificationTrigger- Used for creating a notification at a certain date as in your case and for repeating with specific criteria:

   let date = DateComponents()
   date.hour = 8
   date.minute = 30 
   let trigger = UNCalendarNotificationTrigger(dateMatching: date, repeats: true)
   

The solution (Swift 3) for you would be to convert your date to a dateComponent and this can be done by:

import UserNotifications

var newComponents = Calendar.current.dateComponents([.year,.month,.day,.hour,.minute,.second,], from: date)

let trigger = UNCalendarNotificationTrigger(dateMatching: newComponents, repeats: false)
