Swift has conventions to convert a string into an int

var intString = "10" var myInteger = intString.toInt()! |
But for doubles, lets say you want var dblString = “5.559” converted from a string to a double. You can’t just do dblString.toDouble()!, not going to happen it just gives an error. So the solution for now is to use Objective-C

var dblString = "5.559" var myNSString = NSString(string: dblString) var myDouble = myNSString.doubleValue |
