I think you might need to be subscribed to the mailing-list in order to
post, your other emails are probably sitting in a moderation queue (helps
to cut out a lot of spam).

What do you mean, exactly? I presume you mean disappearing from Xcode...
but disappearing how? Were the .h files there and then just disappeared? Or
did you double-click a .xib in MonoDevelop to launch Xcode and the .h files
weren't created?

You had a backup of temporary .h files? Or what exactly did you restore?
I'm totally lost.

I agree, and if we can figure out what went wrong, I'll do what I can to
prevent this sort of thing from happening again.

I think we can rule out this hypothesis for the issue reported by Chris_M
and the other Chris in that thread (too many Chris's!).

What version of MonoDevelop are you using?

Is Xcode hanging? Or is it MonoDevelop that hangs?

The reference is likely to be in one of your .xib files.

Something quick & easy you can try is going to the Build menu and selecting
"Clean". Then try building and running your app again. It's possible that
an old version of the .xib (or library that references radarB) is still in
the bin directory.

If that doesn't work, then it's likely that one of your .xib files contains
a reference.


Hope that helps,

Jeff
