The context provided does not specifically mention Swift 4.1. However, it does provide a general overview of the evolution of Swift and some key milestones in its development. Here are some relevant points:
-
Swift 3 and Swift 4: Swift 3 was the first version to use the new evolution process and included over 80 language proposals. Swift 4 introduced a new language mode that allowed for incremental adoption, meaning you could mix modules compiled as Swift 3 and Swift 4 in the same program. This approach made it easier for developers to migrate to new language versions.
-
Swift 5: Introduced the stable ABI on Apple platforms, which meant a smaller download size for apps because the Swift standard library was part of the OS itself, optimized for that OS, and shared across all Swift apps and frameworks.
-
Swift 6: Introduced a new language mode that achieves data race safety, expanding Swift's safety guarantees to concurrent programs. It also introduced non-copyable types and a new language subset called embedded Swift for highly constrained systems.

A Swift Tour: Explore Swift’s features and design
Learn the essential features and design philosophy of the Swift programming language. We’ll explore how to model data, handle errors, use protocols, write concurrent code, and more while building up a Swift package that has a library, an HTTP server, and a command line client. Whether you’re just beginning your Swift journey or have been with us from the start, this talk will help you get the most out of the language.
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.
