Yes, I am using Xcode 16 beta 3 on macOS Sequoia beta 3 on both host and guest in the VM. The issue is present when I ran my app in UTM or Apple’s virtualization sample project. I see this issue appear when I run my app, specially whenever it creates thumbnails.
It happens when I use writeHEIFRepresentation and writeJPEGRepresentation, and I’ve tried other ways like ImageIO and AVFoundation which fails the same way.
I recently discovered that setting useSoftwareRenderer to true for CIContext at least let me write JPEG images but not HEIF.
