Convert String to CGFloat in Swift

Question

I\'m new to Swift, how can I convert a String to CGFloat?

I tried:

var fl: CGFloat = str as CGFloat
var fl: CGFloat = (CGFloat)str
var fl: CGFloat = CGFl         


        

Answer 1

in Swift 3.0

if let n = NumberFormatter().number(from: string) {
  let f = CGFloat(n)
}

or this if you are sure that string meets all requirements

let n = CGFloat(NumberFormatter().number(from: string)!)
