I meant to open an old version of my project in xcode 5 and made a change to a xib file then realized that I had opened the newest version of my project by mistake. I then couldn't open the project in xcode 4.6.3 so I went back into xcode 5 opened the xib in IB and under Interface Builder Document, changed Opens in from Xcode 5.0 to Xcode 4.6. Then every time I tried to open the project in 4.6.3, xcode would crash before the project could open. I made a copy of the project folder and now, even though all of the files are in the old project folder, none of them show in xcode 4.6 or 5 when I open the project. None of my images, class files, or anything are showing in xcode even though they are all still in the project folder. Any ideas?
