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

You can make an extension that adds an init to CGFloat

extension CGFloat {

    init?(string: String) {

        guard let number = NumberFormatter().number(from: string) else {
            return nil
        }

        self.init(number.floatValue)
    }

}

Use it like so let x = CGFloat(xString)
