Xcode 4: Auto-complete & Jump to Definition broken in my Xcode 3 Project

Question

My project was created in Xcode 3, I\'m opening it in Xcode 4 and notice the following:

• \'Jump to Definition\' no longer works with my own symbols

Answer 1

I had this exact same issue. I have a project with a bunch of ViewControllers that extend a class I'm calling BaseViewController. I added the following code to BaseViewController.h and syntax coloring and code autocomplete broke! Even with repeated deletions of derived data the problem was still there. I can't believe it!!

@implementation UIView (FindFirstResponder)
- (UIView *)findFirstResponder
{
    if (self.isFirstResponder) {
        return self;
    }

    for (UIView *subView in self.subviews) {
        UIView *firstResponder = [subView findFirstResponder];

        if (firstResponder != nil) {
            return firstResponder;
        }
    }

    return nil;
}
@end

Commenting out this code solved my issues! I have XCode Version 4.4.1 (4F1003)
