objc:ns-string-to-string

(objc:ns-string-to-string ns-string &optional preserve-line-terminators)

The characters of an NSString as a Lisp string. Unless preserve-line-terminators, a CR LF pair and a lone CR each become a newline. Part of the macOS-only objc package -- the interpreter (java -jar, or the rontolisp native binary), a compiled .class / .jar and a --native executable for macOS on Apple silicon, never a .wasm; on a machine without the runtime it signals an error. See the macOS GUI guide.
