Hi @jp.alary,
Without the logs hard to say
In general Iâd suggest you to check this âlocal debuggingâ guide How to debug your build locally / âIt works on my Mac/PC but not on bitrise.ioâ - specifically the Additional notes for iOS projects section (e.g. âMake sure that you run the tests in the same simulator as the one bitrise.io runs.â and âplease make sure to reset the iOS Simulatorâ).
If that wouldnât help probably the easiest way is if you could Screen Share / Remote Desktop into the build VM and run the tests there, and see/debug what the issue might be. Note, please do Reset the Simulator there too if you run more than one test, as thatâs how standard bitrise.io builds work; every build runs in a completely clean VM, and the VM is destroyed at the end of the build, so e.g. the iOS Simulator is always clean.
Guide for how you can connect to the MacOS Build VMs: https://gist.github.com/viktorbenei/c6d4fe1e68de739dbb5f4f15de76b9db
Please let us know how it goes or if youâd have any questions!
