Periodically Unable to Run Unit Tests in Xcode 8

Question

I upgraded to Xcode 8 and I go through hell to run my tests sometimes ... For example, I just tested some code and could run my tests 3 times in a row ... and then for the 4th time I got:

dyld: failed to load the inserted PLATFORM library /iPhoneOS.platform/Developer/Library/PrivateFrameworks/IDEBundleInjection.framework/IDEBundleInjection 'because the image was not found

*** If you think this error is an error, attach the log file to / Users / patrick / Library / Developer / Xcode / DerivedData / MyApp -hjfppqmgxqrprucknvwtakynpqxs / Logs / Test / 2B6C2EAE-5C13-40C9-BACE- 3A00AA74F3ession -UnitTests-2016-09-20_124123-gk3pW0.log

I rebooted my iOS device, rebooted my computer, deleted derrived data, etc. He will no longer run tests. ARRRGH !!!!

UPDATE

I have to mention, I'm trying to run tests on my iPad, I can’t run tests on the simulator because I have too much code related to the built-in NEON functions and therefore the simulator does not start.

But what seems to work when this happens switches to creating tests on my iPhone, and then when it builds, it just says that the “running tests” and the spinner spin forever, but the tests are not actually executed. I can actually click on my application and interact with it, which is usually not the behavior that I get when running tests ... In any case, I stopped the build, switched to my iPad and now the tests run again.
