I would implement that like: zip(names, 1...names.count).forEach { name, index in print("Person \(index) is called \(name)") } Or, in an ideal world: zip(names, 1...names.count) .map({ name, index in "Person \(index) is called \(name)" }) .forEach(print) Currently, that isn't valid Swift, "print" can't be used like that, though if you define a closure it works: let printIt = { x in print(x) } zip(names, 1...names.count) .map({ name, index in "Person \(index) is called \(name)" }) .forEach(printIt) I think that Swift could use = for equality, since assignments return Void and comparison returns Bool. Maybe it should. But your argument boils down to "if you can't be clear everywhere, don't be clear anywhere". That's not a good goal.
