    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.
