swift2 - Using the split function in Swift 2 -

let's want split string empty space. code snippet works fine in swift 1.x. not work in swift 2 in xcode 7 beta 1.

var str = "hello bob" var foo = split(str) {$0 == " "}

i following compiler error:

cannot invoke 'split' argument list of type '(string, (_) -> _)

anyone know how call correctly?

updated: added note xcode 7 beta 1.

split method in extension of collectiontype which, of swift 2, string no longer conforms to. fortunately there other ways split string:

use componentsseparatedbystring:
```
"ab cd".componentsseparatedbystring(" ") // ["ab", "cd"] 
```
as pointed out @dawg, requires import foundation.
instead of calling split on string, use characters of string. characters property returns string.characterview, conforms collectiontype:
```
"😀 🇬🇧".characters.split(" ").map(string.init) // ["😀", "🇬🇧"] 
```
make string conform collectiontype:
```
extension string : collectiontype {}  "w,x,y,z".split(",") // ["w", "x", "y", "z"] 
```
although, since apple made decision remove string's conformance collectiontype seems more sensible stick options 1 or two.

in swift 3, in options 1 , 2 respectively:
