VikR posted a topic in Mac Programming and DevelopmentI'm fairly new to Cocoa and Xcode. My MainMenu.xib file hasn't changed from previous builds, which ran properly. When I run my app, I now get an error message, "Unable to load nib file: MainMenu". I don't have a clue yet about how to deal with this. What are some things I can look at in order to fix this? Thanks very much in advance to all for any info.
