Integrating with Game Center is a great feature for your players. In this chapter, we learned how to create an iTunes Connect record for our app, authenticate Game Center users in our code, create new leaderboards and achievements on iTunes Connect, and then integrate those leaderboards and achievements within our game. We have made a lot of progress!
We are officially finished working on the game itself. In the next chapter, we will prepare our app for publication, upload the code for Apple to review, and revisit what we have learned while creating our great game. Everything is coming together and we are ready to take the final step to publish our game. Congratulations!
