Xcode 10 fails my tests in simulator without any information as to the failure

Since upgrading to Xcode 10 my tests (which before the upgrade passed) are no longer being run as far as I can tell. The build succeeds, then the tests fail, but there is no report to say why.

Originally my target OS was 10.3, but I noticed a greyed out iOS11 in the settings, I have since reverted this to 10.3 with no change.

I have restarted my machine and this doesn't seemed to have helped.

Any insight would be helpful.

I do note that this is the inverse of the problem reported here

Thanks

I had the same problem than you and I've found a solution.

In Xcode go to:

Xcode > File > Workspace Settings...

or

Xcode > File > Project Settings...

Change Build System (in shared workspace settings and in per-user workspace settings) from New Build System (default) to Legacy Build System.

Xcode build system

I hope this will help somebody in the future :)
