Converting CGFloat to String in Swift

Question

This is my current way of converting a CGFloat to String in Swift:

let x:Float = Float(CGFloat) let y:Int = Int(x) let z:String = String(y) 

Is there a more efficient way of doing this?

Answer 1

You can use string interpolation:

let x: CGFloat = 0.1 let string = "\(x)" // "0.1" 

Or technically, you can use the printable nature of CGFloat directly:

let string = x.description 

The description property comes from it implementing the Printable protocol which is what makes string interpolation possible.
