Hey you, a huge congratulations on completing another part of this course. I hope you're enjoying getting into the flow of programming with Swift. So let's review what you've learned in this part. So you learned how to control the flow of operation in your Swift apps. Now, you already knew how to use if else statements, but now you also know several more ways. You can use while loops and repeat while loops to repeatedly execute code while a certain condition is true. And you also learned about for loops and how to use them in combination with ranges to repeat code a certain number of times. You also learned how to use for loops to iterate over the contents of arrays. And finally, you saw how to nest loops inside each other, and you learned how to use continue and break statements to exit out of a loop early. Now we've covered a lot in this part of the course, you're doing a really great job and you're learning a lot about Swift, but coming up in the next part of this course, you'll build on the understanding of collections like tuples and arrays. And you're going to learn about a few more powerful collections in Swift, dictionaries and sets. So thank you for working through this part with me, and I'll see you in the next part of this course.
