+        Overriding breaks some Qt events like `QApplicationStateChangeEvent`. And I suppose (and pretty sure)

+
+        Would be cool to simply inherit `QCocoaApplicationDelegate`, but it's only available in Qt's sources.
+
+        The solution here is to use "method swizzling" technique.
+        We replace the method of a class with own implementation.
+
+        In future we could contribute to Qt to add "continueUserActivity" event.
