Swift property override not working

Question

When I try to override a property I get an error \"can not override mutable property with read-only property\"

I have provided get and set in the super class.

Answer 1

The compiler error message is fairly straightforward: Card's contents property is mutable, which is to say it has a set method in addition to the get method.

Your override only adds a get method, you need to add a set method too.

I think this is what you want:

set(newValue) {
    rankStrings[Int(self.rank)] = newValue;
}
