On OSX (say Yosemite), I'd like a way to call Objective-C from Safari/javascript. Is there a way to do this?
Not what I'm looking for:
embed a WebView/WKWebView in an app
Start/control/load Safari from Objective-C
use JXA outside of Safari (unless it connects in a way that let's me bridge to Objective-C from inside-Safari javascript).
