Bindings Inspector


I have a more general question related to XCode. When I type in the Model Key Path e.g elapsedTime I would expect,
that XCode is clever enough to offer valid possibilities, but it doesn’t. And I am always surprised, that XCode marks my
correct input with a red exclamation mark:

Until now I couldn’t find out what that means and how to avoid this behavior of Xcode.



Sometimes it works and sometimes it doesn’t. I haven’t figured out a pattern to it, so I mostly ignore the error indicator there.



I have the same problem. Because the elapsedTime is not recognized by the binder, the NSProgressIndicator has no response to the timer.
I think it will be a big problem if the binder doesn’t work.
