mutableString
MutableString is a data type in programming languages, particularly within the context of Swift, that allows the contents of a string to be modified after creation. Unlike immutable strings, which cannot be altered once initialized, MutableString provides methods to append, insert, remove, or replace characters within the string. This flexibility is useful in scenarios where strings need to be dynamically constructed or modified, such as building strings incrementally or editing portions of text.
In Swift, MutableString is part of the language’s foundation and is closely related to the String type.
MutableString supports common string manipulation operations, including appending characters or substrings, inserting text at specific positions,
The use of MutableString is particularly relevant in performance-critical applications where string operations are frequent, such
