Really great initiative, I hope it works out well! I haven't taught anyone like this, but in other contexts. I would say since money is involved and he doesn't necessarily have the same strong motivation that self learners usually do that it's important to lay down clear rules, i.e. what does it mean to learn to code. Ideally this should be output based rathe than input oriented, like building a certain simple app. That's also extremely rewarding. I always tell people to follow the stanford course on swift (from itunes u), it's absolutely brilliant. Depending on his background something else might be more suitable, but in any case you could act as the TA checking his homework, but also as a classmate/teacher that can answer questions. The bulk of the presentation of new material you ca safely leave to a mooc i think. Good luck!
