14,618 PointsHello! Yes, in newer versions of Swift there is no characters property on the String type. That's because now instances of String type are arrays in and of themselves. So you can treat them like so and call first right on the string.
Your extension should look like this:
extension Contact {
var firstLetterForSort: String {
return String(firstName.first!).uppercased()
}
}
