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 3.1

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

or:

let fl = CGFloat((str as NSString).floatValue))
