Many thanks for the #include <os/proc.h> workaround and information about os_proc_available_memory(). I'm running into the same issue where it won't compile without that extra line in the bridging header, though it compiles fine for me once I add that extra include. I've also submitted a Feedback with FB10994534. Thanks!

I'm also getting this logged to console. This is with a UIKit app running as a Catalyst on Ventura. A tableview cell contains UIStackViews, and the cells size-to-fit, which I assume is what's causing the issue here (?). Everything runs fine, no crashes, and no idea what this log means.
