xcode 4 debugging shows 'Summary Unavailable' for most objects

Question

Whilst using Xcode 4.0 and trying to debug and see what value is held in what variable - or see what objects are in an array etc, I always seem to get "Summary Unavailable" or "Invalid Summary".

The problem seems much like the one in 3.2.6 if you built and ran a release version with the symbols stripped.

Any chance that any one knows where I am going wrong, or what the resolution is For years things worked smoothly - then Apple stepped in - again.

Thanks

Answer 1

You're not going wrong, Xcode 4 is. This problem is pretty common, unfortunately. Report it at http://bugreport.apple.com/ and hope for the best.

In the meantime you can inspect variables using the console, which appears at the bottom of Xcode 4's window during debugging. If you have an object "myObj", you can inspect it in the console by typing "po myObj". It's a lot less convenient but it's better than not getting the information at all.

Answer 2

You can also try changing the "Summary Format" in the GDB window. Try something like {(NSString *)[$VAR description]}:s as the Summary format - this works for NSManagedObject derived objects.

Answer 3

While waiting for Apple to fix Xcode 4 you can try using "Print Description", which prints the value to console.
