I was trying to make a simple Mac Objective-C application with Xcode to keep score of two players playing a simple game with up to 36 scores per player. It isn't a very practical application because of its limited features, and it's mostly for practice. I was trying to expand the application a bit with a Preferences window, which would pop up when a menu item was clicked.
I created a file to control the men item, then a nib to pop up when it's clicked. All of this worked fine, and a new window would pop up. I put sliders, text fields, etc. on the nib, and connected them to actions. All of that worked fine.
The problem came when I tried to import the files into my root controller so that I could use the user's choices in the application.
I got the following compiler error:
Command /Developer/usr/bin/clang failed with exit code 1
Along with all of this:
