swift2 - Try and catch Error with Parse.com

Question

I need some help with this:

func checkUserCredentials() -> Bool{
      PFUser.logInWithUsername(userName!, password: Contrase?a!)
       if (PFUser.currentUser() != nil){
            return true
        }
        return false
   }

It says that PFUser.logInWithUsername(userName!, password: Contrase?a!) has problems because its not marked with try ... and the error is not handled.

Answer 1

func checkUserCredentials() -> Bool{
    do {
        try PFUser.logInWithUsername(userName!, password: Contrase?a!)
    } catch{
        // deal here with errors
    } 
    return PFUser.currentUser() != nil ? true : false
}

As it is quite basic issue I recommend you reading some tutorials
