Where to Go From Here?

There are numerous other small changes not mentioned here–everything has been updated to valid Swift 3, the Organization and Bundle ID are now specified for Xcode projects and more. Over time, you will see our tutorials and books adopt this style.

We encourage you to read through the entire guide as it is not that long. Also, be sure to check out the API Design Guidelines which is linked from the guide. Finally, it is worth your time to watch the WWDC session about the about the why of API design guidelines.

The style guide has been improved by individuals both inside and outside of raywenderlich.com. I personally would like to thank the many people that have helped this year to make it a better document and added to the discussion. If you don’t see your name in the credits and should be, drop me a line or send a pull request.

This is a living document. If you want to get even more involved, open (or reopen) a Github issue and start a discussion. Typos and errors that need to be immediately fixed will go directly into the master branch after a brief review period. A update branch will handle larger changes for a future update next year. See the contributing guide for more information.
