open twitter app

Actual behavior

Steps to reproduce the behavior

I submitted the app to apple store , each time they rejected it, because the login open musica app instead of twitter

at our phones we don't have musica (and can't find this app at apple store ) so we can login normally .

here is login code :
TWTRTwitter.sharedInstance().logIn() { (session, error) in if let session = session { } }
