[xcode] clang: error: unable to execute command: Segmentation fault: 11

I keep getting the following errors on iOS Cloud Build, my project used to build successfully and if I do a manual build to my phone (instead of a cloud build) it works without errors.

Any ideas what this could be caused by?

14379: [xcode] clang: error: unable to execute command: Segmentation fault: 11
14380: [xcode] clang: error: linker command failed due to signal (use -v to see invocation)
14381: [xcode] ** BUILD FAILED **

Which version of Unity and Xcode do you have selected for that build target? The first thing I would try is manually selecting Xcode 7.3

Unity 5.4.1p1

I’ll try manually selecting Xcode 7.3 now and try again

Thanks, that worked! Interesting that it was that as it was set to use the latest version of Xcode which is 7.3 according to the dropdown list.

Great! And ya, we are in the process of updating of updating which version “latest” is (current it’s 7.2).

I am having this exact problem when building using the iOS Cloud Build service (but not on an independent workstation). How do I specify the Xcode version for a Cloud Build?

select the CONFIG tab from the build.cloud.unity3d.com website page of your game, then open the “Show Signing Credentials” under your iOS settings. And edit the Xcode Version to select Xcode 7.3

Just subscribed to this thread for future updates. :stuck_out_tongue:
I was trying to get an iOS build on Cloud Build with 5.4.f1, but I assumed that the “Use latest Xcode version” means Xcode 8.
I switched to Xcode 7.3 in config, but the webpage showed that my Unity version choice is not compatible with the Xcode version I chose. Is it safe to ignore this for now?

Thank you, found it!
