Good afternoon, do you have two screens correct? and you want it after the valid user goes to your other right view? Go to your Credential View, Hold and Drag the Yellow Ball with Control and place Show,
Follow the screen with an Identifier, put the name you want,
After the code that the user logs in or makes the credentials just put below the code:
self.performSegueWithIdentifier("NomeDoSeguimento", sender: self)
A simple example is the Login of facebook, after it logs, just put down the perfomrSegueWithIdentifier, that it goes to the view that you put the Segue ..
Do not forget to create follow-up!
In my case it's showLogin! With this code you can send the user to the View you want as long as you put the right name in the Identifier!
I hope I have helped!
