What is the benefit of this? I am asking because my main system is stuck on macOS 14 and the older Xcode version.

Can't you still use Xcode 16?

We need to keep up with Xcode releases somewhat, otherwise we cannot use newer functions. For example, Apple added WKWebView.obscuredContentInsets which I want to use to replace the private methods we use. Swift does not have preprocessor macros like __MAC_OS_X_VERSION_MAX_ALLOWED.

We might have to drop Xcode 16 too if we intend to use the new app icon format for macOS 26.

I think I'm actually stuck on Xcode 15.4 but since I don't have much time these days it doesn't matter, if you need higher Xcode versions then go for it!

It should still work with Xcode 16.2 which runs on macOS 14.5. I will leave the GitHub Action at version 16.4 though just to ensure that it still builds with the last release.
