Next steps

- [Instructor] I hope you enjoyed the course and now you've got the taste of how powerful protocols can be. If you are interested in more Swift content, you should probably check out other intermediate courses in our library. I suggest you check out Swift 3 Essential Training: Beyond the Basics. This course also mentions protocol-oriented programming. Also, you might want to check out iOS 11 Development Essential Training: Application Architecture. Another great resource is Apple's own documentation.

You can download The Swift Programming Language Swift 4 edition for free from the iBook Store. You can find me on LinkedIn, Twitter, YouTube, and my blog. Thanks again for watching.
