system-preferences

I am developing a FinderSync extension and I have some issues in checking if the selection is selecting, or selecting/deselecting the extension. Is there a way to programmatically check if a FinderSync extension is selected in System Preferences->Extensions ? Are there any API's to get notified when this selection changes?

Well that's great, but now, I want to add a new Cocoa subclass using Swift. Accepting
