Just fixed it. xcodebuild -downloadPlatform iOS -architectureVariant arm64 just run that in terminal and it will download and appear in Xcode

Same here. Maybe unrelated but I noticed I installed the apple silicon Xcode and it's trying to install "ios 26.0 Universal Simulator (23A5308g)". Other (watchOS, tvOS, etc.) runtimes download fine it seems. I also do have an iOS 18.5 runtime installed but no other platforms so curious if that has something to do with it

Same issue here. Tests are passing locally, and even appear to all pass in the attached logs. However XCC is reporting this same failure at the end of the run.

Also seeing this. Our builds are giving: Command exited with non-zero exit-code: 128 fatal: unable to access 'https://github.com/my-project-repo.git/': The requested URL returned error: 502 Your SCM service 'github.com' failed to respond, please check that it's available and while resolving package dependencies they all: error: RPC failed; HTTP 502 curl 22 The requested URL returned error: 502
