Class without subclassing NSObject in Swift

Question

Anyone can tell me when we can create a class without subclassing NSObject?

*With*: access to the ObjC runtime. *Without*: no access. – vadian Jan 22 '18 at 07:42 — vadian, Jan 22 '18 at 07:42

"NSObject is the root class of most Objective-C class hierarchies. Through NSObject, objects inherit a basic interface to the runtime system and the ability to behave as Objective-C objects."

As this would suggest, you need to subclass NSObject for types introduced in your code whenever instances of that type need to behave like an Objective-C object (or the class itself, in some rarer cases).
