SwiftNone

SwiftNone is a concept in programming, specifically in the Swift language, representing an absence of a value or "nothing." It is used to indicate that a variable or function does not have or return any meaningful data, similar to “null” or “nil” in other languages. SwiftNone helps developers handle cases where a value might be missing without causing errors, enabling safer and clearer code. It’s a way to explicitly state that no value exists, ensuring programmers are aware of situations where data is unavailable or not applicable.
