I am having one of those moments where a process I've done dozens of
times mysteriously stops working. I hope somebody can point me in the
right direction.
The problem: an Xcode 2.4 project (starting with Core Data document-
based template) refuses to let me debug my unit tests. I get a
complaint from dyld (1, below) and a crash log (2, below).
Xcode runs the tests when I build the test bundle, no problems. But
when I try to debug the test that is failing, I get rejected as
described above.
The steps I took to debug the tests are the same as always:
1. Create a custom executable, with the same path as my regular app.
(Verified that it launches without the special test-injection voodoo,
so the path is not wrong.)
2. In my custom executable's inspector in Xcode, I added the args "-
SenTest All" and these two environment variables, with the values
shown below them:
(I did confirm both those evaulate to the correct, existent paths.)
3. Press Run in Xcode. Blammo, it crashes.
4. Clean All (dependencies included), Rebuild, try again
5. Just for fun, quit Xcode, rebooted the Mac, and re-did the above
steps. Same result, though.
6. Just to see if it would really crash, I disabled the extra arg and
the XCInjectBundle environment variable: still crashed. So the only
thing needed to make this thing crash is to add the
DYLD_INSERT_LIBRARIES environment variable with the value $
(SYSTEM_LIBRARY_DIR)/PrivateFrameworks/
DevToolsBundleInjection.framework, but that is the exact same value
that I always use (sucessfully in other projects).
7. Downloaded and installed Xcode 2.4.1, but alas, no change...
Now, I have pored over the project for the better part of an hour,
and I just cannot find anything to make this different than the
several other Xcode projects on this Mac for which debugging unit
tests works fine. The only difference I can see is that none of the
others were Core Data document-based apps, but that should not matter...
What could I be missing that would cause an error loading
DevToolsBundleInjection.framework for this project? Some kind of
weird build setting or something? I am back to caveman debugging with
NSLog() until I get some kind of clue...
Thanks,
