Property wrappers in Swift are a powerful feature that encapsulate logic for managing stored values. They allow you to intercept calls to read and write a property, implementing reusable logic that can be applied with a simple annotation. For example, the argument property wrapper from the Swift ArgumentParser package can be applied to a property to designate that it stores the value of a command line argument. This makes it easier to build expressive, type-safe APIs and reduce boilerplate code in your applications.
