Tap Local Notifications isn't triggered

Question

In iOS 10.3 I'm adding the code, to the AppDelegate:

@interface AppDelegate () {
    UNUserNotificationCenter *center;
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    center = [UNUserNotificationCenter currentNotificationCenter];
    UNAuthorizationOptions options = UNAuthorizationOptionAlert + UNAuthorizationOptionSound;
    [center requestAuthorizationWithOptions:options
                          completionHandler:^(BOOL granted, NSError * _Nullable error) {
                              if (!granted) {
                                  DLog(@"Something went wrong");
                              } else {
                                  DLog(@"Access Granted")
                              }
                          }];

    return YES;
}

I tap the notification but the method bellow isn't called.

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification

For Register for notification import UserNotifications/UserNotifications.h framework in AppDelegate and use Notification Delegate UNUserNotificationCenterDelegate to respond to notifications when notifications receive.

@interface AppDelegate ()<UNUserNotificationCenterDelegate>

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.

    //Notification Setup.
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 10.0) {
        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
        center.delegate = self;
        [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error){
            if( !error ){
                [[UIApplication sharedApplication] registerForRemoteNotifications];
            }
        }];
    } else {

        //register to receive notifications
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound) categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];

    }


    return YES;
}
