Photo Extensions are supposed to be supported on Mac Catalyst in Monterey, but when I try, I get an error from Xcode.
I'm using the WWDC seed of Xcode 13. (Version 13.0 beta (13A5154h)
error: 'PhotoExtension.appex' is a Photo Editing extension, which is not available when building for Mac Catalyst. You may need to restrict the platforms for which this app extension should be embedded in the target editor. (in target 'CatalystTest' from project 'CatalystTest')
Has anyone gotten this to work?
