WatchOS App 4.0: How to schedule a local notification

Question

My application in background or inactive mode then local notification not work. I have never receive local notification on watch.

Update: less then 3 minutes schedule a local notification it's work fine but more then 3 minutes it's not work. so how to resolve this issues?

As per my understanding My code is as follows.

UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
center.delegate = self;

// Objective-C
UNMutableNotificationContent *content = [UNMutableNotificationContent new];
content.title = [NSString localizedUserNotificationStringForKey:@"Remider!" arguments:nil];
content.body = [NSString localizedUserNotificationStringForKey:@"Your watch is out of range" arguments:nil];
content.sound = [UNNotificationSound defaultSound];

// Time
// 15 min
double timer = 15*60;
UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:time
                                                                                                repeats:NO];
// Actions
UNNotificationAction *snoozeAction = [UNNotificationAction actionWithIdentifier:@"Track"
                                                                          title:@"Track" options:UNNotificationActionOptionForeground];

// Objective-C
UNNotificationCategory *category = [UNNotificationCategory categoryWithIdentifier:@"UYLReminderCategory"
                                                                          actions:@[snoozeAction] intentIdentifiers:@[]
                                                                          options:UNNotificationCategoryOptionCustomDismissAction];
NSSet *categories = [NSSet setWithObject:category];

// Objective-C
[center setNotificationCategories:categories];

// Objective-C
content.categoryIdentifier = @"UYLReminderCategory";

NSString *identifier = [self stringUUID];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:identifier
                                                                      content:content trigger:trigger];

[center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
    if (error != nil) {
        NSLog(@"Something went wrong: %@",error);
    }
}];

Appreciate if any suggestion or idea.

Make sure your iphone is locked. When it comes to notification, its about preference where to deliver that notification.

Run your watch app on simulator, from iPhone simulator schedule the notification and lock the iPhone simulator screen, keep the watch simulator active, in that case when notification is triggered , it will be delivered on your watch simulator. Same will be the case when you will test on actual devices. Source Link

And when both iphone and watch is locked, preference is iphone.

UPDATE

Notification on Apple Watch
