解説
This is a convenience method for classes that adopt the NSCopying protocol. An exception is raised if there is no implementation for copy(with:).
NSObject does not itself support the NSCopying protocol. Subclasses must support the protocol and implement the copy(with:) method. A subclass version of the copy(with:) method should send the message to super first, to incorporate its implementation, unless the subclass descends directly from NSObject.
