The link error is pretty self-explanatory. To solve issues like this,
I'd first change the header like so:
extern NSString *const someString;
and create a SharedDefs.m:
NSString *const someString = @"halla";
This way, any object file can reference someString, but only one
object file will actually define it - SharedDefs.m. And voila, link
errors be gone.

Hi David,
I understand the message, and I thought of the solution you
suggested. What I'm puzzled with is that I thought #import only
imports once.

Duh... never mind. The header *is* being imported only once, per .m
file. That's not the problem. The problem is that
NSString* const someString = @"foo";
creates two strings with the same reference name, one for AppDelegate
and one for SomeClass. It wasn't until I typed the message above that
I realized my mistake.
I think I should go have lunch now. My brain is lacking some food....
