How do I use generic constraints with multiple classes?
Take a look ContainerAB, please.

class ClassA {}
class ClassB {}
class ClassC {}

class ContainerA<T> where T: ClassA {
    var object: T
    
    init(object: T) {
        self.object = object
    }
}

class ContainerAB<T> where T: ClassA & ClassB {
    ...
    ...
    ...
}
