Today I tried to work on an old application and received this message:
"This version of Interface Builder does not support documents such as" Interface Builder Cocoa Touch Document (XIB 3.x) "for" iPhone / iPod touch ".
I have never had this before and just can imagine what happened after I updated my system to OS X Lion yesterday.
What should I do now? Looks like I can’t edit any of my old applications? How can I update xib files so that they work with Lion?
