To use property wrappers in iOS Swift, you can encapsulate logic for managing stored values by intercepting the calls to read and write a property. This allows you to implement reusable logic that can be applied to a property with a simple annotation.
For example, in the session A Swift Tour: Explore Swift’s features and design, property wrappers are discussed as a way to build expressive, type-safe APIs and eliminate boilerplate code. A property wrapper can be applied to a property to manage its stored value, as demonstrated with the argument property wrapper from the Swift ArgumentParser package, which designates that a property stores the value of a command line argument.
If you want to see this in action, you can check out the session A Swift Tour: Explore Swift’s features and design starting at the "Extensibility" chapter.
