Pod linking error raised when do Swift unit test on XCode7 if enable "Gather coverage data"

I do a simple swift project using XCode7.3. Everything is ok, UI & Unit test run properly too. However, when I wanna see coverage data, I can not run unit test anymore

ld: framework not found Pods_MapView
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Would you please give me a clue?

P/S: I hostes my project at http://ift.tt/1UFsmhw
