  • Adding `as NSNumber` should help, compare http://stackoverflow.com/questions/39321421/working-with-nsnumber-integer-values-in-swift-3 or http://stackoverflow.com/questions/39493898/nsexpression-nsnumber-extension-changed-in-swift-3-0 – Martin R Sep 15 '16 at 18:55

var correctGuesses = 10
var totalGuesses = 20

var result = NSNumber(value: correctGuesses / totalGuesses)

let percentString = NumberFormatter.localizedString(
  from: result,
  number: NumberFormatter.Style.percent
)

Or simply, for not add another var

let percentString = NumberFormatter.localizedString(
from: NSNumber(value: Double(correctGuesses) / Double(totalGuesses)),
number: NumberFormatter.Style.percent)
