Can't static functions with parameters in Swift be used in ObjectC code?

I'm wondering if static parameter functions created in Swift can't be used in ObjectC.

xcode version is 15.1 (15C65)

Yes, this should work:

@objc class MyClass: NSObject {
    @objc static func foo(_ param: Int) {}
    @objc static func bar(param: Int) {}
void test(void) {
    [MyClass foo:42];          // ✅
    [MyClass barWithParam:24]; // ✅

The obj-c name could be customised if needed if you don't like the name made by default.
