This course is part of our iOS and Swift for Beginners learning path. You're ready for this course if you're working through that learning path in order, or you're someone who has just a little bit of Swift experience.

To start, you'll review some function fundamentals and learn more advanced features of functions. You'll also practice writing closures, a close relative of functions, and using them to manipulate collections.

Then, you'll move on to build your skills in writing named types: structures, classes, enumerations, and protocols. You'll learn about the features they share, and some of the functionality that makes each unique.

Throughout the course, you'll practice everything you learn with hands-on challenges.

This course isn’t suited for advanced developers. If that’s you, check out our Advanced Swift Courses for more ways to level-up your Swift skills!
