Swift: declaration 'description' cannot override more than one superclass declaration

Question

I have a structure of inheritance similar to the one below. I\'m adopting the Printable protocol and diligently override description property. I have encountered a bizarre error

Answer 1

What is the Printable Protocol? ;-)

You could use a Getter of a property as

var description: String {
    get {
        return "This is a test";
    }
}
