Yes, this should catch all the exceptions that you missed in your app. Considering that you obviously are not catching many exception somewhere else and are looking for a simple solution, this event handler might work, but I seriously don’t recommend it.

This event handler catches the exceptions and then should crash/quit your app. If you handled your exceptions only here, this would lead to a huge crash count. Sometimes exceptions happen, but the app can continue working normally. That’s why I recommend that you handle them as they happen in your code, and not here. That way you have a full control of how your app continues and if it continues at all, and reduce the number of “unhandled exceptions” and app crashes.
