Hi nedbryn,
Your questions is very broad to be honest.
Exactly, where are you up to in the process?
There are a couple of great posts on here about IOS.
Such as https://hub.jmonkeyengine.org/t/my-experience-with-jme-on-ios/31192
and
https://jmonkeyengine.github.io/wiki/jme3/ios.html#toolbar
Let me know where you are up to in the process and I’ll help if I can.
Thanks,
Anthony,
