Macro that automatically conform enumeration to a protocol where all case associated values conforms to this protocol

[YiJiang (蒋艺)]

protocol MyProtocol {
    func foo()
    func bar()
}

struct MyStruct1: MyProtocol {
    func foo() { }
    func bar() { }
}
struct MyStruct2: MyProtocol {
    func foo() { }
    
    func bar() { }
}

enum StructHolder: MyProtocol {
    case first(MyStruct1)
    case second(MyStruct2)
}

has anyone write a macro that automatically conform StructHolder to MyProtocol?

From my understanding, in embedded swift, I can't use let array: [any MyProtocol] so I want to use let array: [StructHolder]. But this way I have to repeat all methods with a switch case pattern.
