Since updating to Studio, I seem to be getting the error: "The operation could not be completed. No other information is available about the problem" when I double click on a XIB file. If editing just the visual aspects, I can usually just ignore this error and navigate to the XIB file in the project that is opened in xcode. However, if I want to create or link up the outlets, it looks like I'm screwed. Anybody else seeing this? It seems like MonoDevelop is now having the same problem.
