@stepanhruda Indeed, you're right. I left this in because Kiwi does have some dependencies on SenTestingKit; not including SenTestingKit.framework in the podspec causes two sets of linker errors:

1. `KWFailure.m` references the `SenTestFilenameKey` and `SenTestLineNumberKey` constants
2. `SenTestSuite (KiwiAdditions)`

Of course, neither of these are important to projects using XCTest. We could use string literals in place of the string constants, and only include the `SenTestSuite` patches in the "Kiwi/SenTestingKit" subspec. Here's a gist of the changes: https://gist.github.com/modocache/6576139 The gist moves the `SenTestSuite` category to its own folder and only includes that folder in the SenTestingKit subspec. Should I add this to the PR?
