Pathfinding using ARKit

I've been looking for a solution to work with Pathfinding and ARKit but I don't know if I'm working in the proper way to find a solution.

Before, I worked with Pathfinding using AR through Unity, using NavMesh to avoid obstacles, so, I can move from an starting node to an ending node.

Now I'm taking a look to work on a Pathfinding using SpriteKit and after that, translating to 3D.

Which solution do you recommend me to use?

Thanks!
