Job ID: 31095047

Budget: $30 – $250 USD

I have a completed Augmented Reality Unity project that I would like to update from 2018.4.2 to 2020.3 and ARFoundation, ARKit to the latest versions. I have tried this myself, however, I am not able to resolve all compile errors because I am not as technically savvy.
