objc:string-to-ns-string

(objc:string-to-ns-string string &optional autoreleasep)

An NSString holding string. The program owns it: objc:release gives it up; with autoreleasep it goes to the current autorelease pool instead. 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.
