The problem of crash is about not having proper observer. As per
https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/Notifications/Articles/NotificationCenters.html
NSNotificationCenter delivers notifications to observers synchronously whereas NSDistributedNotificationCenter
notification is usually delivered to the main thread’s run loop, thus not depending on observer setup. Both will work
but since we use NSNotificationCenter in mac so far, it seems prudent to use the same methodology for this case too, so
I have rectified the observer setup.
