We covered a lot of ground in this tutorial, not least seeing how we can lean on powerful frameworks like Core Image to introduce impressive graphical effects. Yes, it never quite made the smooth leap to Swift – you need to know it’s quirks if you want to make the most of it. Still, you’re through the worst of it now, so hopefully you can try using it in your own code!
At the same time, we also learned some great SwiftUI stuff, including confirmation dialogs, onChange()
, ContentUnavailableView
, and App Store reviews, all of which are super common and will continue to be useful for years to come.
Anyone can sit through a tutorial, but it takes actual work to remember what was taught. It’s my job to make sure you take as much from these tutorials as possible, so I’ve prepared a short review to help you check your learning.

One of the best ways to learn is to write your own code as often as possible, so here are three ways you should try extending this app to make sure you fully understand what’s going on.
Tip: That last one might be a little trickier than you expect. Why? Maybe have a think about it for 10 seconds!
