- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void(^)(NSArray<id<UIUserActivityRestoring>> * __nullable restorableObjects))restorationHandler NS_AVAILABLE_IOS(8_0);
which handles deep link delegate has userActivity which one of its properties is referrerURL which returns always nil
My guess is it should contain the referrer app or website data that launched the deep link.
NSUserActivity docs: nsuseractivity
referrerURL docs: referrerurl
my question is how can I receive a correct referrerURL and not nil?
