A static string is a string literal that is stored in the program's memory throughout its execution. In iOS (and generally in programming), such strings are usually placed in a read-only memory segment and are not modified.

For example, a string defined directly in the code:

let greeting = "Hello, World!"

greeting is a static string that exists in memory permanently and can be reused multiple times without additional memory allocation.

This differs from dynamically created strings, which can be modified and managed on the heap during program execution.

Static strings are efficient in terms of memory and access speed, as they are created once and reused.
