Answer 1

From apple documentation:

Swift provides a default initializer for any structure or base class that provides default values for all of its properties and does not provide at least one initializer itself. The default initializer simply creates a new instance with all of its properties set to their default values.

Your class ilStringProperty is not a base class as it inherit from ILProperty so it must have an initializer, if you create one or override one does not matter since you have at least one initializer in your class as swift will not give one for free.
