    It might be too late to answer this question, but this might be helpful. Let’s say you’ve already installed the Twitter SDK in you iOS app. You can get Twitter user’s info like this:

    1. Login with twitter:

    Twitter.sharedInstance().logIn(completion: { (session, error) in }

    2. Use the TWTRAPIClient to retrieve user’s data:

    Twitter.sharedInstance().logIn(completion: { (session, error) in 
    guard let session = session else {
        print("Something went wrong.")
        return
    }        

    let client = TWTRAPIClient()
    client.loadUser(withID: session.userID, completion: { (user, error) in
         print("user's name: (user?.name ?? "")")
         print("user's profile picture: (user?.profileImageURL ?? "")")
    })
}
