Generated on 9/24/2024

Property wrappers in Swift are a feature that allows developers to encapsulate logic for managing stored values. They work by intercepting the calls to read and write a property, implementing reusable logic that can be applied to a property with a simple annotation. This feature helps in building expressive, 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.

Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.
