Hi yeldarb! This is a really neat app. I don't want to diminish your creation, so please don't think I'm trying to put you down with this question: How much of this was just glue-code to integrate a few modules, vs. how much did you have to do from scratch? I'm asking to try to get an idea to see if ARkit is within the reach of an average joe- sudoku solver code could be a copy/paste, digit recognition could be a copy/paste, and ARKit should provide you with some environment/location info.

It's mostly glue (but some of it is special glue). Oddly enough, digit recognition was one of the harder parts. iOS11's Vision API has character recognition but it only gives you a bounding box, it doesn't do the OCR! So for that I ended up ripping up a whole bunch of Sudoku puzzle books from the second hand book store and scanning them in to create a dataset. Then I trained my own nerual network in Keras and converted it to CoreML. The actual ARKit part was really easy, even for me who has never done iOS programming before.
