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

While the other answers are correct, but the result you see will have trailing decimals.

For example:

let str = "3.141592654"
let foo = CGFloat((str as NSString).floatValue)

Result:

3.14159274101257

To get a proper value back from the string, try the following:

let str : String = "3.141592654"
let secStr : NSString = str as NSString
let flt : CGFloat = CGFloat(secStr.doubleValue)

Result:

3.141592654
