Convert unicode symbols \uXXXX in String to Character in Swift

I'm receiving via a REST API a string which contains unicode encoded characters in form of \uXXXX

e.g. Ain\u2019t which should be Ain’t

Is there a nice way to convert these?

Solution

  • You can use \u{my_unicode}:

    print("Ain\u{2019}t this a beautiful day")
/* Prints "Ain’t this a beautiful day"

    From the Language Guide - Strings and Characters - Unicode:

    String literals can include the following special characters:

    ...

    • An arbitrary Unicode scalar, written as \u{n}, where n is a 1–8 digit hexadecimal number with a value equal to a valid Unicode code point
