I wrote an application for OSX 10.6.8 a month or two ago. It worked fine. I used XCode 3.2.6 to write it and had a bunch of .h and .m files with IBOutlets and IBActions that I connected easily to the buttons and stuff they had to reference. XCode 4.4 comes along when I upgrade to Mountain Lion and suddenly everything is broken. I have found absolutely nothing of help on the internet. The closest I've come to finding a solution is someone telling me to change the "File's Owner" to a different class, which makes absolutely no sense as I have almost 10 unique classes with their own IBOutlets and IBActions. Ok so, since I can't explain it well, the project is set up like this: When I try to connect outlets, actions, and references, it only gives me the option to connect "bindings." And when I did (for fun) change the class of File's Owner to "OpenReadMe" instead of NSApplication, it threw that error message in the bottom right (though I did finally get the darn thing to compile) What exactly am I missing? I have NEVER found myself confronted with a piece of Apple software that is hard for me to use and doesn't strike me as intuitive.
