How did we do? We’d love to know your thoughts on this year’s conference. Take the survey here
Hello,
I'm getting started for my project with Xcode Cloud since I upgraded to the macOS Sequioa Beta and Xcode 16 now refuses to archive builds for TestFlight.
Somewhere very late in the build process I get the following error:
realitytool requires Metal for this operation and it is not available in this build environment
The log says this happens at:
Compile Skybox urban.skybox
My project uses RealityKit. How can I fix this issue?
Thanks!

I have the same issue. The use of Metal for my project had to deal with "compiling" an exr skybox file. The workaround is to generate a the compiled skybox file locally (a realityenv file) and check that into your repo. My workaround has a "Run Script" in Xcode right after the compile source phase to do this step and an Xcode Cloud Environment Variable called XCODE_CLOUD.
if [ "$XCODE_CLOUD" = "true" ]; then
exit 0
fi
$DEVELOPER_BIN_DIR/realitytool compile --platform iphoneos --deployment-target 18.0 -o=$PROJECT_DIR/MyProject $PROJECT_DIR/Source/MySkybox.skybox
Okay great, devforums threw away my post when trying to reply here... Trying again.
I'm getting this error too and it's super frustrating. If I could pay for GPU instances, or if I could provide my own hardware to Xcode Cloud, then this wouldn't be an issue. But now this is forcing me off of Xcode Cloud, since there's no way for it to build my project on it.
Anybody else found any workarounds? I don't think I can apply msanford's trick, since it's failing generically on my rkassets bundle and won't even tell me which asset requires GPU to compile.
