This week I published the biggest ever update to SwiftUI by Example, adding lots of new sample code plus 100 new Xcode projects to download.

The initial goal was to update the book for iOS 16, but I ended up going back and adding coverage of functionality introduced in iOS 15 and even 14 – this update is just packed with extra code, improved examples, and more.

To save you having to dig through and look for what’s new, here’s a list of the biggest changes:

• All navigation examples have been updated to use NavigationStack and NavigationSplitView.
• New: How to customize the background color of navigation bars, tab bars, and toolbars.
• New: How to adjust List row separator insets
• New: How to hide the tab bar, navigation bar, or other toolbars
