@frozen struct String

Overview

A string is a series of characters, such as "Swift", that forms a collection. Strings in Swift are Unicode correct and locale insensitive, and are designed to be efficient. The String type bridges with the Objective-C class NSString and offers interoperability with C functions that works with strings.

You can create new strings using string literals or string interpolations. A string literal is a series of characters enclosed in quotes.
