Sample of XCode canceling builds when using sourcery

Steps to reproduce:

1. Bundle install
2. Pod install
3. Open XCode
4. Run Tests

Expeted:

Run the tests

Actual:

Build Canceled

Notes:

I was able to reproduce this for the vast majority of the cases, but it's still an intermittent behavior. So if you manage to run the tests please delete the CodeGenerated folder and generated files in it, then go to step 4 one more time.
