Spell out ordinal numbers

There are few ways to generate short ordinal numbers like "1st", "2nd", etc, with NSNumberFormatter (from iOS 9) or 3rd parties like FormatterKit.

There is also a way to spell out cardinal numbers with NSNumberFormatter that gives one, two, three.

However, I need to get the unabbreviated spelling - first, second, third.

I know that iOS internally can do it, because if I pass "1st" to AVSpeechUtterance it pronounces it as "first". I was wondering if there is any API to get a string with spelling of ordinal numbers, preferably, for multiple languages?

Solution

  • I couldn't find an existing libraries for that, so I created my own.

    It uses ICU4C underneath from the system libraries. Before using, please check how the example project works:
