Nick Walter spent four days reading Apple’s documentation of the newly-released programming language Swift, “kind of translating into English and giving some extra examples.” Apple announced its release on June 2, and four days later Walter posted 50 videos, or one full course, to the online education site Udemy. It was an introduction to Swift for beginners, called Swift By Examples. That first month, his course earned him $45,000. Udemy charges students a set price — in this case, $99 — to access the online course as many times as they want. If these students find the course through a link sent by Walter, he gets 97% of the money. If they find the course through Udemy, he splits the money 50/50 with the company.
