How can I get the length of a String in Swift 2.0?

Question

So far it was:

let string = "my example string"
if count(string) >= 3 { ... }

But now I get an error:

count is unavailable: access the count property on the collection. Type String doesn't conform to protocol CollectionType

Answer 1

哦，很简单：

string.characters.count

Answer 2

Again more simplified version

In Swift 4.0 and Above

let strLength = string.count

Answer 3

It should be like that

let string = "my example string"
let length = string.characters.count

Because in Swift 2.0 Apple changed global functions to protocol extensions.
