Swift, Apple's preferred application language, used UTF-16 to store strings until version 5 which switched to UTF-8. [36] Quite a few languages make the encoding part of the string object, and thus store and support a large set of encodings including UTF-16. Most consider UTF-16 and UCS-2 to be different encodings.

In response to a message it receives, an actor can: make local decisions, create more actors, send more messages, and determine how to respond to the next message received.
