Analogous mechanisms used in Swift are related to mutation semantics and value/reference types:
Value Types: Swift structs, enums, and tuples are value types. When a value type instance is assigned to a new variable or passed as a function argument, a copy of the data is created. Changes to the new copy do not affect the original, similar to how making copies of copyrighted material allows independent modification of the copy without altering the original.
swiftCopy-on-Write (COW): Many built-in collection types (Array, Dictionary, Set, String, Data) implement Copy-on-Write semantics. This is an optimization where multiple va
