IOS10.3 localnotification objective-c - ios

Question

I wanted to create a local Notification in IOS 10.3 using objective -c for a certain date of date picker, but it is not working for some reason.
here is my code
-(IBAction)addReminder:(id)sender
{
NSDate *date =self.datePicker.date;
UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc]init];
content.title = [NSString localizedUserNotificationStringForKey:#"wake up" arguments:nil];
content.body = [NSString localizedUserNotificationStringForKey:#"it is time" arguments:nil];
NSDateComponents *dateComponent = [[NSDateComponents alloc]init];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *Components = [calendar components:NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitMinute fromDate:date];
dateComponent.hour = [Components hour];
dateComponent.minute = [Components minute];
UNCalendarNotificationTrigger *trigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:dateComponent repeats:NO];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:#"Alarm" content:content trigger:trigger];
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
// Ask user for the permission
[center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert + UNAuthorizationOptionSound)
completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted)
{
// Add your notification to center
[center addNotificationRequest:request
withCompletionHandler:^(NSError * _Nullable error) {
if (error != nil)
{
NSLog(#"%#", [error localizedDescription]);
}
NSLog(#"finished scheduling");
}];
}
else
{
NSLog(#"%i",granted);
}
}];
}
After I run my code and I choose a certain date. The notification does not work and I get 0 for "granted variable" in the console.
