This is driving me nuts. I've configured my project to have unit tests, and the tests run fine. But when I have a test failure, the iOS developer documentation example shows that the error should be shown in the editor window. This for me doesn't happen, I have to drill down through the build output window to find the error. I've seen a few posts on Stack Overflow about this, but no one with solutions. Anyone here with any clue what might be happening?
