As you may know we have our iOS SDK Extension for FileMaker iOS SDK.
We are working on an update to support notifications in the FileMaker iOS SDK:
So you can create local notifications in FileMaker, define title, subtitle, body, badge number and more. Than you add a trigger based on time (Seconds in future), date or a location. We can also receive remote push notifications, if you setup it correct on the server side.
This should be available in a few weeks for everyone to try.
