Hello,

I keep getting this error every time I try to build my iOS game with Xcode(10) - Unity 2018, done some research but have yet to find a solution/reason for the issue. Anyone else has issue or any ideas?

Thanks!

I'm having the same issue. I'm building to an iPad 3rd gen on iOS 9.3.5 from a $$anonymous$$acBook running $$anonymous$$ojave. I was not able to find any xcworkspace file either. Any help would be appreciated.

This could be happen if you try to run your project in simulator instead of real device. @garv3

Hi guys. Still on this issue. $$anonymous$$y project doesn't generate a workspace file. I tried to attach a print screen here but it didn't work. But, believe me. I know what kind of files you mentioned and it is not here. I must add that everything runs perfectly on my devices when I compile the project on Xcode. The problem is specifically with the archiving process. I really hope you can help me. $$anonymous$$ore than 24 hours with this problem. Thanks

Hi guys.

I've been researching almost the whole day. Did you find any other solution?

I'm using Unity 2018.2.15.f1. Our App is an ARFoundation project. My Xcode is 10.1 (10B61). Everything works, but when we used Xcode to post our work to Apple Connect we get this error:

linker command failed with exit code 1 (use -v to see invocation) clang

I really appreciate any suggestion.
