This repo contains the code for Secret Lab's book, Learning Swift, 3rd Edition.
In Learning Swift, 3rd Edition, you create Selfiegram, an app that makes use of several features of iOS, including working with the file system, capturing photos, and performing image analysis with the Vision framework. This repo contains the source code used in the book, as well as the playground that contains the general explanation of Swift that appears in Part 1 of the book.
You can buy Learning Swift at these fine purveyors of books:
- O'Reilly Media (direct from the publisher!)
- Amazon
If you're reading Learning Swift, 3rd Edition, you can use this repo to check your own code against what we made. If you just want to play with some code, you can fire up Selfiegram.xcodeproj and take a look!
Please note: this repo contains the final version of the app. We deliberately designed the app so that you spend more time adding code than you do replacing code, which means that if you browse the code in this repo, you'll probably see more code than you've written so far.
Throughout the code in this repo, you'll see little tags like this:
// BEGIN tuples
let aTuple = (1, "Yes")
// END tuples
These BEGIN and END markers are used during the production of the book to include snippets of code into the final book. This ensures that the code that appears in the book is identical to what's in the repo (at least, what was in the repo when the book went to print.)
You can safely ignore the snippet tags - they don't do anything to the code. However, if you're interested in our snippet system, it's available on GitHub.
We hope that you find this repo useful. If you have issues, please either open an issue, or send us an email.
Unfortunately, we aren't taking contributions for this repo, because it was designed as a partner for a printed book, so accepting changes would likely throw it out of sync with the dead-tree version, leading to confused readers. However, you're strongly encouraged to fork the code, and make your own, even better version!
