In April 2022, Kodeco published the first edition of macOS by Tutorials . Nothing stays the same in the world of Apple development, so I started to plan an update after WWDC 2023. At around that time, Kodceo was going through a transformation from being like a library to being more of an educational institution. Their focus is now on multi-modal courses and they are no longer interested in publishing books.

Kodeco agreed to transfer the rights of the macOS by Tutorials book to me, since it was out-of-catalog and since then, I have been working on an update which is almost ready for release. I had hoped to have it out before WWDC 2024, but real-life has a habit of getting in the way, and that was not possible.

The book is now available at Gumroad .

If you previously bought the book from either Kodeco or Amazon, please email me for a 50% discount code. I am unable to provide a free update for the Kodeco version, but I will provide free updates subsequently for the self-published version.

Every project in this book has been updated to macOS 14 Sonoma and Xcode 15. They have also been tested using Xcode 16 beta 3.

The major changes in this edition include:

• The On This Day app uses NavigationSplitView instead of the older NavigationView.
• On This Day implements the new Observation framework for its data.
• The Time-ato app no longer imports the external LaunchAtLogin package but now uses Apple’s ServiceManagement library.
• Creating an app intent in ImageSipper uses the new code-based system.
• The workflow for distributing your app has been updated to reflect the changes in App Store Connect and Xcode.

As I am now a self-publisher, I will be able to release more timely and incremental updates and will incorporate the latest changes to macOS, Xcode Swift and SwiftUI as they are released.
