# string(withCString:length:) Returns a string containing the characters in a given C-string. ``` class func string(withCString bytes: UnsafePointer, length: Int) -> Any? ``` ## Discussion `cString` must not be NULL. `cString` should contain characters in the default C-string encoding. This method converts `length` * `sizeof(char)` bytes from `cString` and doesn’t stop short at a `NULL` character. ## See Also --- Copyright © 2026 Apple Inc.
