Using ARcore on iOS? + AugmentedImages

I’ve been using ARcore - building from source provided in the Google ARcore Github FAQ / Startup guide.

I have it all working using the ARcore templates provided by Google - the HelloAR + AugmentedImages namely. These I have got successfully working with custom images, custom rendered 3D content on a Pixel 2XL.

I was wondering if anyone had tips, links or advise on how to use ARcore with iOS? Perhaps some way of integrating ARkit as well as ARcore? Not really sure where to start.

All I really want to achieve is be able to scan an image on an iOS device and have geometry tracked to it.

ARCore can be used on iOS too. It simply uses ARkits tracking data under the hood.
Workflow in UE4 should not require changes to your code, it still is ARCore.

To package for an iOS device you need an apple developer account and a Mac.
