To create a Swift CLI for performance, you can follow several key principles and leverage the tools and features discussed in various WWDC sessions. Here are some steps and considerations based on the content presented:

  1. Understand Swift Performance:

    • Optimization: Swift has a powerful optimizer, but the way you write code can significantly impact its effectiveness. Regularly monitor performance and automate measurements to identify regressions (Explore Swift performance).
    • Low-level Principles: Gain an intuition for the performance of different operations in Swift, especially compared to languages like C (Explore Swift performance).
  2. Build and Test Efficiently:

    • Build Improvements: Xcode has made improvements to how it builds Swift code, which can help in reducing build times and improving debugging (What’s new in Swift).
    • Cross Compilation: You can build Swift packages on macOS and deploy them on Linux servers, which is useful for creating cross-platform CLI tools (What’s new in Swift).
  3. Leverage Swift on Server:

  4. Migrate to Swift 6:

    • Data-race Safety: Swift 6 introduces full data isolation enforcement, which can help in writing safer and more performant code (Migrate your app to Swift 6).

By following these guidelines and utilizing the resources from the WWDC sessions, you can create a high-performance Swift CLI. For more detailed information, you can refer to the specific sessions mentioned above.

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.
