Swift only way to prevent NSKeyedUnarchiver.decodeObject crash?

Question

NSKeyedUnarchiver.decodeObject will cause a crash / SIGABRT if the original class is unknown. The only solution I have seen to catching this issue

Answer 1

another way is to fix the name of the class used for NSCoding. You simply have to use:

• NSKeyedArchiver.setClassName("List", forClass: List.self before serializing
• NSKeyedUnarchiver.setClass(List.self, forClassName: "List") before deserializing

wherever needed.

Looks like iOS extensions prefix the class name with the extension's name.
