So, I read this post, and it's pretty much exactly what I was looking for. However... it doesn't work. I guess I'm not going to go with the singleton object, but rather making the array in either a Global.h file, or insert it into the _Prefix file.

Both times I do that though, I get the error:

Expected specifier-qualifier-list before 'static'

and it doesn't work. So... I'm not sure how to get it to work, I can remove extern and it works, but I feel like I need that to make it a constant.

The end goal is to have this Mutable Array be accessible from any object or any file in my project. Help would be appreciated!

This is the code for my Globals.h file:

#import <Foundation/Foundation.h>


@interface Globals : NSObject {
    static extern NSMutableArray * myGlobalArray;
}


@end

I don't think I need anything in the implementation file. If I were to put that in the prefix file, the error was the same.
