Builds for testing fail when code coverage is enabled

Originator:brennan
Number:rdar://31228255 Date Originated:23-Mar-2017 02:35 PM
Status:Open Resolved:
Product:Xcode Product Version:8.2.1
Classification:bug Reproducible:Always
 
Summary:
I am unable to build due a linking error only when I build for testing when code coverage is enabled. If I turn off code coverage the build for testing is successful. I have added 2 framework targets with their own test targets which may be a contributing factor.

Steps to Reproduce:
1. Create a new iOS app project with a test target
2. Add an external Xcode project as a dependency
3. Add a framework target with tests
4. Add another framework test with tests
5. Enable code coverage in the build scheme
6. Build for testing

Expected Results:
The build should be successful for building the app target with or without test targets.

Actual Results:
Linking fails to the external project dependency. 

Version:
Xcode 8.2.1

Notes:
This is yet another reason many developers working with Xcode use as an excuse for not adding tests. Overcoming these build errors is time consuming and costly and ultimately it affects users who either end up using crashy apps or do not get features which were cut due to time wasted with getting Xcode to work.

Reproducing the problem

I've assembled an Xcode configuration with multiple build targets and embedded libraries to try to recreate the problem. So far it is not failing. I've included notes at the bottom of the README.md about ways that the bug could be reproduced.
