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?

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.
The fast way:
let x = CGFloat(12.345)
let s = String(format: "%.3f", Double(x))
The better way, because it takes care on locales:
let x = CGFloat(12.345)
let numberFormatter = NSNumberFormatter()
numberFormatter.numberStyle = .DecimalStyle
numberFormatter.minimumFractionDigits = 3
numberFormatter.maximumFractionDigits = 3
let s = numberFormatter.stringFromNumber(x)
