Benefits of using NSObject in Swift

NSObject is the base class for all Objective-C classes. In Swift, NSObject is used as the base class for all classes that inherit from Objective-C. This allows Swift classes to be used with Objective-C APIs and interact with other Objective-C objects.

One of the main benefits of using NSObject as the base class for your Swift classes is that it allows your classes to be easily interoperable with Objective-C code. This is important because many of the frameworks and libraries available for iOS and macOS are written in Objective-C, and being able to use these frameworks and libraries with your Swift code can greatly expand the capabilities of your app.

Another benefit of using NSObject is that it provides many of the fundamental behaviors and features that are common to all objects in Objective-C, such as dynamic typing, introspection, and the ability to add properties and methods at runtime. This can simplify the development process and make it easier to implement common design patterns in your app.

Overall, using NSObject as the base class for your Swift classes is a key part of bridging the gap between Swift and Objective-C and allowing your Swift code to take advantage of the rich ecosystem of libraries and frameworks available for iOS and macOS.
