First steps in Swift

As Mark Twain once said, “the secret to getting ahead is getting started.” Well, you’re starting now, so we’re going to dive in and learn about variables, constants, and simple data types.

Today you have eight one-minute videos to watch. If you want to dive deeper into each topic there is optional further reading, but you don’t need to read that unless you want to. Regardless, once you’ve finished each topic there’s a short test to help make sure you’ve understood what was taught.

I know, I know: the temptation is strong to continue on to watch more videos and take more tests beyond those linked below, but remember: don’t rush ahead! It’s much better to do one hour a day every day than do chunks with large gaps between.

  1. Variables
  2. Strings and integers
  3. Multi-line strings
  4. Doubles and Booleans
  5. String interpolation
  6. Constants
  7. Type annotations
  8. Simple types: Summary

When you’re finished, don’t forget to tell other people about your progress. Yes, this is only day one, but the more motivation you get now the more you’ll be able to power through when things get tougher!

Reminder: I have a free iOS app that helps you practice Swift right on your iPhone and iPad. It contains the same lessons and tests as above, plus lots more bonus activities. And did I mention it was free? Download it here.

  • You can download Xcode from the Mac App Store by clicking here.
  • As you progress in these early days you’ll build up lots of code from each day. You can keep it in different playgrounds if you want, or you can delete it – it’s down to you.
