A very good talk that tells you to forget about all the fancy features that complicate Swift, go back to basic “for” loops, and think about your code!

Something I am trying to preach …

@tuparev I wouldn’t say “forget about all the fancy features,” I would say “think about what they actually do.”

The fancy features, used well, often yield code that is both fast and readable.

For UI, yes, sometimes. For model classes - almost never.
