# set A representation of the set containing the contents of the ordered set. ``` var set: Set { get } ``` ## Discussion This returns a proxy object for the receiving ordered set, which acts like an immutable set. While you cannot mutate the ordered set through this proxy, mutations to the original ordered set will be reflected in the proxy and it will appear to change spontaneously, because a copy of the ordered set is not being made. --- Copyright © 2026 Apple Inc.
