I use Teamcity as my build server, and I have multiple agents, and an agent has multiple Xcode versions installed on it.


Just as I started to use Xcode7.3 on my build agents, I randomly run into a build issue. When I run into this issue, I see similar entries in the build log :

I am not sure but maybe when this issue occurs, I have muliple "xcodebuild"s running at the same time on the agent with different Xcode versions.


Do you have any idea how could this issue be solved?


Thanks for your help in advance!

You should really be asking such questions of them, not in these forums which are dedicated

to Apple tools.

Hi,


I am having the same issue, and it seems that different versions of Xcode (in my case 7.3.1 and 8-beta) are starting different versions of CoreSimulatorService and that Xcode checks if it can deal with the one that is there. If it cannot, if registers its own but then crashes for some reason.

I was not able to resolve it, but was wondering:


cssz - you mention you have a setup where multiple xcode versions are executing xcodebuild in parallel.

How do you solve the problem of multiple simulators opening?


Best regards,


Florian

Hi all,


I run a Jenkins-based CI system that also makes use of build servers with multiple xcode versions running and installed, and we've been running into this a bit.


I filed a bug report with Apple that was marked as a dpulicate of issue 26303087


Running these commands before a build seems to be a hacky way to get around this problem. In the below, " /Applications/Xcode[VERSION].app" is the path to your xcode installation. 


sudo -S xcode-select -s /Applications/Xcode[VERSION].app/Contents/Developer echo

sudo chmod -R g-w $(xcode-select -p)/Library/PrivateFrameworks/CoreSimulator.framework/Versions/A/XPCServices/com.apple.CoreSimulator.CoreSimulatorService.xpc echo

sudo chown -R root:wheel $(xcode-select -p)/Library/PrivateFrameworks/CoreSimulator.framework/Versions/A/XPCServices/com.apple.CoreSimulator.CoreSimulatorService.xpc


I've yet to see the error after adding those commands to the start of a build.

I do the following before switching Xcode:

launchctl remove com.apple.CoreSimulator.CoreSimulatorService


to fix such kind of issue:

CoreSimulator is attempting to unload a stale CoreSimulatorService job.  Detected Xcode.app relocation or CoreSimulatorService version change.  Framework path (/xcode_7_3/Xcode.app/Contents/Developer/Library/PrivateFrameworks/CoreSimulator.framework) and version (209.19) does not match existing job path (/xcode_7_2_1/Xcode.app/Contents/Developer/Library/PrivateFrameworks/CoreSimulator.framework/Versions/A/XPCServices/com.apple.CoreSimulator.CoreSimulatorService.xpc/Contents/MacOS/com.apple.CoreSimulator.CoreSimulatorService) and version (201.3).
