Description Paul Johnson 2013-07-29 11:53:11 UTC
Using - business edition, Mac OS X 10.8.4, X.S. 4.1.7, Xcode 4.6.1

There looks to be a regression error going from the 6.3.x branch to 6.4.x whereby ViewControllers are losing everything and not being recognised as ViewControllers. Typically it is only seen when compiling and a ViewController is not recognised.

When the XIB is then selected and the connections viewed, there are no connections and no ability to add connections. The designer.cs file is empty as well (it appears as a blank file). The only way to get the connections back is to create a new view controller and copy the old design over and relink the connections.

This seems to have been caused by my VirtualProjectPath lookup optimization that was new in 4.1.7 and should be fixed in 4.1.8

Looks like it is currently broken in 4.3.0

Do you have a test case for this?

This bug seems to have cleared the system now. I'll close it.

I just encountered this same in 5.7 (build 661).  Some of the details were slightly off.  For example the .designer.cs file was not empty.  Also in IB the .h file was not empty.  However the symptoms were that my UIViewController derived class could not be implicitly assigned to window.RootViewController, and deleting / recreating the ViewController fixed it.
