Error : 'No known class method for selector 'didReceiveNotificationResponse:' when following documentation

I've been trying to setup notifications on an IOS app for several days and I'm facing many issues.

In appDelegate.m :

I followed the installation directions but doesn't work for me ...

Thanks in advance

try with ` // Define UNUserNotificationCenter

UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert + UNAuthorizationOptionSound + UNAuthorizationOptionBadge)completionHandler:^(BOOL granted, NSError * _Nullable error) { if (granted) { center.delegate = self; } }];`

Didn't work ☹️

So? Any news? I guess it's only the example code that is off, but I have no clue whatsoever about native iOS stuff

[ogbodo]

any solution yet?
