Yes, i did use that same pattern. And if you want to, you can kind of force Swift to do this (String! is an "unwrapped optional" and can be nil or have a value) but it feels unnatural. You definitely have to design a bit differently than ObjC. Luckily Swift's enums are amazing and you can return multiple values (through tuples), so there are great ways to return different types of values. |
