objc:coerce-to-objc-class

(objc:coerce-to-objc-class class)

The class pointer a class name designates; a class pointer is answered as it is. A name no loaded image defines signals an error. One object per class, so two answers for one class are eq. 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.
