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

Use the Swift native types whenever you can. In the case of String, however, you have "seamless" access to all the NSString methods like this:

var greeting = "Hello!"
var len = (greeting as NSString).length
