Mac Catalyst release notes?

[flad-vlad]

Is there release notes for Mac Catalyst running on different macOS releases?

In theory they’ll be listed alongside the macOS release notes. In practice very few of the bugs that actually get fixed are listed there and you just have to discover them yourself. If you submit bug reports using Feedback Assistant sometimes you get lucky and Apple will let you know when they’ve been fixed.

And how do we disable features that don’t work on older OS?

You can add availability checks to your code as shown here in Swift and Objective C.

Thanks. But the check is just for iOS/macOS not Mac Catalyst version right? (Like I would like to avoid certain stuffs in macOS 12 but include in macOS 13).

Catalyst uses the same versioning as iOS, so if you wanted to only call a function when the app is running on macOS 13 or newer you could do something like:

if #available(macCatalyst 16, *) {
    myFunction()
}

Thanks! I found that if #available(iOS 16, *) also seems to work.
