Unable to use custom class in a protocol with @objc attribute?

Question

I am trying to create a protocol for JSON loading delegation, JSONLoaderDelegate. My other class, called JSONLoader, is supposed to dispatch events

Answer 1

I faced this problem as I had a class MyConnection that had no parent class. Like this.

public class MyConnection {
}

I can't put @objc before this, as I get a warning

Only classes that inherit from NSObject can be declared @objc

So I changed the class to be inherited from NSObject. Like this

public class MyConnection: NSObject {
}
