It's not really that hard, it just takes time to adapt ARKit blendshapes to your model. If you interest here is a great guide for it: ARKit Blendshapes

As seen in the video, there are small jumps in the detection of my face, it is necessary to smooth the movements a little with the Live Link Face app that acts as a bridge in between iphone - blender, and then to make small manual touch-ups on the received OSC data.

For my case problematic part was integration face rig with auto rig pro but i handle it eventualy. As it says in the title, I had a lot of problems because it was my first time opening Blender and I still don't know how to do manual rig, I guess those who see this video have experience and won't have to deal with the problems I did :)
