does string and function is a reference type?

In Swift, strings and functions have different type semantics:
-
Strings: In Swift, strings are value types. This means that when you assign a string to another variable or pass it to a function, a copy of the string is made. This is part of Swift's emphasis on value types and immutability, which makes it easier to reason about code, especially in concurrent programming. You can see this discussed in the session A Swift Tour: Explore Swift’s features and design.
-
Functions: Functions in Swift are reference types. When you assign a function to a variable or pass it to another function, you are passing a reference to the function, not a copy of it. This is explained in the session Explore Swift performance, where it mentions that function values in Swift are a pair of a function pointer and a context pointer.
