This is what I really liked about Paul Hegarty’s iOS dev course. His projects sort of deliberately walk students into the common pitfalls so that you can try to figure out a fix on your own and then he explains what/why/how Swift behaves that way. He doesn’t deliberately teach you incorrectly but he’ll set up the project in such a way that when he asks you to add X he expects the vast majority will think “oh I just do this” which doesn’t work because the real answer is a bit more involved. Bonus: when you start spotting the pitfalls ahead of time it’s super motivating!
