Over the past months, we have now labored onerous at updating our e-book Pondering in SwiftUI. Over the previous years, we had the prospect to conduct SwiftUI workshops for a lot of corporations. Based mostly on this expertise and the suggestions we obtained, our strategy to explaining SwiftUI has advanced loads. Subsequently, we selected to do a full rewrite of the e-book to be on par with our workshops.

The overall construction nonetheless is similar to the earlier version, however the content material is model new. We put a whole lot of emphasis on explaining view bushes (which in actual fact would be the first chapter of the e-book) on this re-creation, in addition to how view bushes are interpreted when it comes to state, format, animations, and extra. The e-book contains loads of latest diagrams to visualise these ideas.

After WWDC, we have been a bit torn about what to do. Ought to we put out a e-book with out mentioning all the brand new issues? This is able to be bizarre for those that can goal iOS 17 / macOS 14. But rewriting the complete e-book for iOS 17 solely can also be not an choice, as many people nonetheless must help older platforms. As an alternative, we selected to amend the present chapters with callout packing containers, declaring related modifications. As well as, we’ll have a separate iOS 17 chapter in the interim. For the ultimate launch of the e-book (as soon as the brand new stuff is out of beta) we’ll attempt to combine the contents of that chapter into the remainder of the e-book.

As a consequence of this transition section, we have determined to launch the brand new version as a beta model. We plan to place out the chapters one-by-one as we’re integrating new iOS 17 subjects. Throughout this prerelease section, we’re additionally internet hosting a weekly Q&A dwell stream. The first dwell stream will probably be in the present day (Friday June sixteenth) at 18:00 GMT+1 (9am PST). You possibly can submit any questions you’ve for us over at this Github repository.

Till now we have now up to date all of our books free of charge ever since we began objc.io (over ten years in the past!). Since this replace of Pondering in SwiftUI will not be an incremental one, however an entire rewrite from the bottom up, we have determined to launch it as a brand new product – the prelease model is offered now.
