Yes, Swift Testing supports lazy properties for setup. In Swift Testing, the types initializer is used for setup purposes, and it can be async or throw. This allows for the use of lazy properties to perform setup logic before each test runs. Additionally, deinitializers can be used to perform logic after each test, but they are only applicable when the suite type is an actor or class. This setup approach is part of the design to integrate seamlessly with Swift concurrency and to encourage the use of structs to isolate state.

What’s new in Swift
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.
