Cannot run tests on Xcode 6 Beta 5

Question

I have an iOS project that is using the Kiwi testing framework (latest version 2.3.0 which I installed from cocoapods). At first when I ran the tests I received an error that it cannot find XCTest.h. So I followed the advice on this answer: https://stackoverflow.com/a/24651704/1082326 and the problem went away.

However a different problem arise, now when I try to run the tests when the simulator selected is "iPhone 5 (8.0)" then I get the following error:

IDEBundleInjection.c: Error 3587 loading bundle

The bundle “teacup-tests.octest” couldn’t be loaded because it is damaged or missing 
necessary resources.

Do you know what could be the issue?

Thanks in advance, Ido

I have solved this problem by setting code signing as "Don't Code Sign" and cleaning the project (Cmd + Option + Shift + K).
