Property wrappers in Swift are a feature designed to encapsulate logic for managing stored values, allowing you to implement reusable logic that can be applied to a property with a simple annotation. This feature is particularly useful for building type-safe APIs and reducing boilerplate code in applications.
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 is demonstrated in the session titled "A Swift Tour: Explore Swift’s features and design" from WWDC 2024. You can see this in action in the session at the timestamp 23:24.
If you're interested in learning more about how property wrappers can be used in Swift, you might want to explore the session "A Swift Tour: Explore Swift’s features and design" which covers various extensibility features in Swift, including property wrappers.
