Swift Convert comma separated string to NSMutableArray

Question

I have the following string

var points = "4,5"

I would like to convert to a mutable array so it becomes [4,5] I tried the following but it did not work

   var points = "4,5" 
   var selectedArray : NSMutableArray = [points]

Answer 1

Swift 2:

Here you go:

var points = "4,5"
var pointsArr = split(points) {$0 == ","}

or

var pointsArr = points.componentsSeparatedByString(",")

Swift 3:

as gomfucius mentioned:

var arr = points.components(separatedBy: ",")
