Hi according to the documentation we can have Message extensions in Mac Catalyst 14+, and that the MSStickerBrowserView is supported from Mac Catalyst 13.1+. But it doesn't seem possible to actually build an extension app, or Sticker extension, embedded in a Mac Catalyst app and have it appear in macOS messages. Error: iMessage Applications are not available when building for Mac Catalyst. and error: iMessage / Sticker Pack extensions are not available when building for Mac Catalyst. With the announcement for macOS Sonoma that the Stickers will be available in Mac Messages, is this finally going to be possible? If this isn't possible, why is there support for Mac Catalyst?

I have upgraded from macOS 12.5.4 to macOS 13 Beta 1. Haven't done anything odd. I am attempting to use WeatherKit but I am getting a lot of (odd) errors: The sample can't access the ~/Library/Weather/ folder despite it being set to read for users, others and group. (I've since switched to read and write for all, but no dice). Lots of other odd errors. 2022-06-11 22:52:26.720487+0100 PlayWithWeatherKit[16282:277975] [WeatherService] Couldn't get access to the /Library/Weather directory for the geocode Store. error=Error Domain=NSCocoaErrorDomain Code=257 "The file “Weather” couldn’t be opened because you don’t have permission to view it."
