Similar issue here. Running macOS Sequoia Beta and Xcode 16 Beta inside a UTM VM. Everything downloaded OK apart from the Predictive Code Completion Model.

Hey @crreed we have a similar problem - 2 custom apps stuck in "175 Processing". Regarding your second post above, could you explain in more detail what you did to fix the problem? We have also reached out to Apple with no response :( Thanks!

We too have encountered something similar on Ventura Beta 11 and Xcode 14.1 Beta 3, but which works perfectly on older macOS versions. In our case, we are setting an NSWindow's contentView to a NSHostingView to host a SwiftUI view. Full-screen kiosk mode is successfully invoked via enterFullScreenMode(...), but when later calling exitFullScreenMode(...) we found this did not work. With some debugging, it appears that contentView becomes nil after full-screen kiosk mode is invoked. I've worked around this by storing the contentView in a temp var before invoking kiosk mode, then later checking if contentView is nil - and if so set contentView = temp var - before calling exitFullScreenMode.
