Languages that dump crap into the namespace on import are doing the wrong thing. Python has from x import * and every style guide says to never use it. Swift has a lot of other nice features, but the import thing is really a bungle. It is worse for everyone, beginners and experienced users alike. It is even bad for IDE users because you can't type imported-thing.<tab> to get the autocomplete for just the import. You're stuck with the whole universe of stuff jamming up your autocomplete.
disclaimer: I use swift, but also I have used python.
