In this insightful video, Yuki Aki, a distinguished iOS Engineer from LINE, takes you on a deep dive into the "any" and "some" keywords introduced in Swift 5.7 and their critical roles in modern Swift programming. As Swift continues to evolve, understanding these keywords becomes essential for creating efficient and performant Swift APIs. Through a detailed exploration of the Swift Compiler, including the special mechanisms of "Existential Container" and "Existential Type," this presentation unveils the secrets behind the performance and runtime behavior of these keywords. Whether you're aiming to refine your Swifty API design or curious about the deep workings of the Swift Compiler, this video is your gateway to mastering "any" and "some" in Swift. Dive in to discover how these keywords can revolutionize your Swift code and lead to module optimization, ultimately enhancing your development process.
