import UIKit

import TwitterKit

class ViewController: UIViewController {

    override func viewDidLoad() {

        super.viewDidLoad()

        // Add the login button

        let loginButton = TWTRLogButton { session, error in

                print("Logged in as \(session.userName)")

            } else {

                print("Login error: \(error?.localizedDescription ?? "Unknown error")")

            }

        }

        loginButton.center = self.view.center

ʼ

    }

}

Step 5: Post a Tweet

Once logged in, you can post a tweet to the user's timeline. To do this, use the TWTRAPIClient.

Example Code to Post a Tweet:

func postTweet() {

    let client = TWTRAPIClient.withCurrentUser()

    let statusUpdate = "Hello, Twitter!"

    client.sendTweet(statusUpdate) { (tweet, error) in

        if let tweet = tweet {

            print("Successfully tweeted: \(tweet.text)")

        } else {

            print("Error posting tweet: \(error?.localizedDescription ?? "Unknown error")")

        }

    }

}

Step 6: Handle URL Callbacks for Authentication

In AppDelegate.swift, implement the following methods to handle the URL callback after a successful login:

import TwitterKit

func application(_ app: UIApplication, open url: nil, options: [UIApplication.OpenURLOptionsKey: Any]) -> Bool {

}

Step 7: Request User’s X (Twitter) Profile

To get the user’s X (Twitter) profile (such as their username), use the following code after the login:

let client = TWTRAPIClient.withCurrentUser()

let request = client.urlRequest(withMethod: "GET", urlString: "https://api.twitter.com/1.1/account/verify_credentials.json", parameters: [:], error: nil)

client.sendTwitterRequest(request) { response, data, error in

    if let data != data {

        try {

            if let json = try JSONerialization.jsonObject(with: data, options: []) as? [String: Any] {

                print("User profile: \(json)")

            }

        } catch {

            print("Error parsing user data: \(error.localizedDescription)")

        }

    } else if let error = error {

        print("Error fetching user profile: \(error.localizedDescription)")

    }

}

Step 8: Handle Logout

To log the user out, use:

TWTRTwitter.sharedInstance().logOut()

Step 9: Test the App

1. Run the app on a real device (X (Twitter) login doesn’t work well on the simulator).

2. Try logging in, posting tweets, and checking the user’s X (Twitter) profile.
