Swift version: 5.1
As of iOS 9.0, Apple introduced a simple way to make ordinal style numbers, which is a fancy way of saying 1st, 2nd, 3rd or 100th – the kind of numbers you normally write for dates, for example. This uses the
NumberFormatterStyle.ordinal style of writing numbers with
NumberFormatter, like this:
let formatter = NumberFormatter() formatter.numberStyle = .ordinal let first = formatter.string(from: 1) let second = formatter.string(from: 2) let tenth = formatter.string(from: 10) let oneThousandAndFirst = formatter.string(from: 1001)
