Programming in Swift: Fundamentals

I’m so happy you made it through that last section! Really well done — I’m proud of you. Dictionaries and sets are more complex collections, for sure, but you’ll come across them time and time again in your development career.

You’ve learned quite a lot in this course about some of the building blocks of creating and working with collections:

You started with the tuple (or tuhple, however you pronounce it),

Then you took those concepts and applied them to dictionaries and learned how key-value pairs work.

And you finished off with sets, and learned some advanced concepts like union and intersection.

Don’t underestimate what you’ve covered so far — you’ve learned quite a lot in just a short time!

There’s just one more section left in this course; section five covers Swift methods, functions and what’s known as “named types”; once you’ve made it through that last section of this course, you’ll be ready to take on the next course in this series, “Your Second iOS App”.

You’re nearly done – I’ll see you in the next section!
