They finally added support for push notifications on the simulator, this is awesome for us developers.
Looks like 11.4 is a good release, the push stuff was on my wish list but I didn't expect it to be launched on a mid year release.
I imagine it would create the option for a bundled discount (if so desired). Should also add a little competition among similar apps across all platforms. For example, the bundled price for ToDoist vs Things.
