So congratulations for making it through your introduction to collections. You've also learned quite a lot about some of the building blocks of creating and working with collections. You started with the small tuple or tuple, however you pronounce it. You then moved on to creating arrays, populating arrays, and retrieving those elements from those arrays, and you also learned how to look up information about arrays, such as their length and whether or not they're empty. And finally, you even learned how to manipulate arrays and move items around inside that array. Great job, you! Your next stop is the third section of this course, which will take a little break from working with collections and take a deeper look at something you've learned about when you built your first IOS app, control flow. You'll look at a concept known as looping, which, coincidentally, you can use to work with the arrays you've learned how to build in this section. It's almost like we planned it that way. So I'll see you in the next section. Bye for now.
