After successful Mac upgrade, Xcode 27 works but my Xcode 26.5 and also Xcode 26.6RC show a no entry overlay on the icon and a launch alert saying not supported. I did get it to launch by opening the App Package Contents and opening the Xcode inside the MacOS Folder. So you theoretically can submit to the App Store from MacOS 27.0 The behavior of the icon needs fixing. Yes they were both the Apple Silicon Xcode downloads.

I have my app accepting images shared from Photos but from the screenshot editor, my app icon does not show as a destination for the screenshot. Do I have to build an app extension or app intent catcher to then pass along the screenshot? It the problem that the screenshot editor is a modal sheet holding my app interface. I want to catch the screenshot in background for processing.

Many years ago I put an attribute named throws in a core data entity. Now I want to extract the data and move it to a new swift data with more function. I try to rename the entity to avoid compile problems with throws being a swift keyword, now banned as a SwiftData field. I need a code path to extract from the original core data using swift. The SwiftData macros seem to choke on the throws keyword and substitute blanks. DB rename of the attribute still uses the original throws name at the code level.
