objc:define-objc-class-method

(objc:define-objc-class-method (name result-type [result-style]) ((object-var class-name [pointer-var]) (arg-var arg-type [arg-style])*) form*)

Defines the class method name of a class objc:define-objc-class defined, as objc:define-objc-method defines an instance method. object-var is bound to the Lisp class, pointer-var to the Objective-C class, and (objc:current-super) sends to the superclass's class methods. 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. The definition needs no runtime: the Objective-C side is made when the runtime is opened (objc:ensure-objc-initialized, or the first send). See the macOS GUI guide.
