Comment(by watson1978@…):

 And same method has been implemented in NSString for compatibility with
 Ruby.

 {{{
 irb(main):001:0> str = NSString.stringWithString("foo")
 => "foo"
 irb(main):002:0> str.count
 ArgumentError: wrong number of arguments

 irb(main):003:0> str.count "o"
 => 2
 }}}

 You might need to avoid "count" method.
