3D model formats in ARKit / ARCore development

Question

I am a beginner at AR game development for both iOS and Android. I have the following questions:

1. What kinds of 3D model formats are supported by ARKit for i

Answer 1

ARcore itself doesn't come with any 3d model handling logic at this moment. To render a 3D model in any format, you need to parse the data and draw it using openGL. The sample app in the package demonstrates how this can be done for a simple 3D model i.e 1 OBJ and 1 texture file.
