Add an "s" to the end of a string, depending on a variable

Question

I'd like to append an s to the end of a string, if the value of a variable is > 1.

There are obviously several ways to accomplish this - for example:

if(points == 1) {
     points_as_string = "1 Point"
} else {
     points_as_string = "\(points) Points"
}

A shorter version could be:

points_as_string = (points == 1 ? "1 Point" : "\(points) Points")

An even shorter version would be:

points_as_string = "\(points) Point" + (points == 1 ? "" : "s")

Is it possible to write something even shorter than that, or is that as good as it gets?

For proper pluralization in multiple languages you would use NSLocalizedString and .stringsdict files, see https://developer.apple.com/library/ios/documentation/MacOSX/Conceptual/BPInternational/LocalizingYourApp/LocalizingYourApp.html#//apple_ref/doc/uid/10000171i-CH5-SW10.

Only very slightly shorter:

points_as_string = "\(points) Point\(points == 1 ? "" : "s")"

Here is a shorter version that uses a dictionary lookup and the nil coalescing operator ??:

points_as_string = "\(points) Point\([1:""][points] ?? "s")"
