Swift - which types to use? NSString or String

Question

With the introduction of Swift I\'ve been trying to get my head round the new language

I\'m an iOS developer and would use types such as NSString, NSInteger, N

Answer 1

String and NSString are interchangeable, so it doesn't really matter which one you use. You can always cast between the two, using

let s = "hello" as NSString

or even

let s: NSString  = "hello"

NSInteger is just an alias for an int or a long (depending on the architecture), so I'd just use Int.

NSDictionary is a different matter, since Dictionary is a completely separate implementation.

In general I'd stick to swift types whenever possibile and you can always convert between the two at need, using the bridgeToObjectiveC() method provided by swift classes.
