Hi,

I believe this has been discussed on trac already, although I can't seem to find the ticket.

In short, this is expected behavior. A method added to the String class will only be available to strings created from Ruby. If you want a method to be available to all strings, add it to the NSString class. I do agree that this can be confusing behavior and maybe we can try to reduce the confusion somehow. This design was implemented in 0.6 and is the result of several debates. I personally didn't expect people would notice this :)

  20      assert cocoa_string.respond_to?(:my_method), "cocoa_string.respond_to?"

  21    end

  22

  23  end

What is the expected result of line 20?

On the one hand cocoa_string is an NSString so the monkey patch shouldn't have any effect, but on the other cocoa_string is claiming to be a ruby String.
