Property 'count' not found on object of type 'NSMutableArray *' PO command in lldb

Question

I'm using the console to po some variables, in this case I have a NSMutableArray, I want to see its count. I get a wonderful error.

Any ideas?

I am aware I can see the count in the variable list (it says @"1 object"), but I seem to have this error for multiple getters and properties while using po.

UPDATE: Seems like the square bracket notation is the key, and casting to int makes it readable.

Have you tried casting the variable? (`po (NSMutableArray *)myarray`). I think this is a bug/missing feature in the debugger. — trojanfoe, Nov 26 '12 at 15:07
In fact no need to cast, but to get a "human" friendly display you need to cast to int. — Andy B, Nov 26 '12 at 16:55
