DAY 13

Swift review, day one

Congratulations! You made it through all the fundamentals of the Swift programming language. Each video was purposefully very short to give you a lightning-fast introduction to the topic, but for the next three days we’ll be slowing right down so you can consolidate what you’ve learned.

This means we’ll be going over the fundamentals of Swift again, but this time more slowly and in more detail.

I know what you’re thinking. You’re thinking “why bother? I already learned this stuff – why go over it again?”

Well, there are several reasons:

  • Repetition helps us learn things more thoroughly. These fundamentals are really important in all the Swift you’ll write, so it’s worth doubling down to make sure you understand them fully.
  • Some concepts only make complete sense when you’ve understood other concepts. Circling back like this will help link together the core Swift concepts in your head.
  • You might have missed something. Let’s face it, you’ve just gone through 100 videos about the most important parts of Swift – are you absolutely sure you remembered all of it?
  • You’ll see how far you’ve come. When you read about arrays and loops – things you might have found challenging previously – hopefully you’ll find them easier now, and feel good that you’re making progress.


Today you have nine topics to review. Once you’ve completed them you can, if you want, go back over the tests from earlier days to improve on your scores.

  1. Variables and constants
  2. Types of Data
  3. Operators
  4. String interpolation
  5. Arrays
  6. Dictionaries
  7. Conditional statements
  8. Loops
  9. Switch case


Optional: once you’ve finished reviewing those, you can go back to the review page and go over the tests related to the topics above.
