How to convert a string to a float

Paul Hudson    September 15th 2016    @twostraws

There are several ways to convert between a string and a Float, but the easiest way is to use NSString as an intermediate because that comes with several helpers built right in:

let myString = "556"
let myFloat = (myString as NSString).floatValue

Available from iOS 7.0
