Improved Compatibility: Swift Version 6 Enhances Collaboration with C++, Adds Support for RISC-V, and Enhances Performance on Windows and Linux.

Apple’s Swift language project released version 6.0 with improvements on various language aspects such as:

Enhanced concurrent operations: more accurate data race detection, decreased false positive warnings, but still requires manual activation to use.
Typed throws: declaring functions with specific mention of potential throws.
Better integration with C++: now supports virtual methods, default arguments, and various types.
Embedded usage: utilizing language features for Arm and RISC-V architectures.
Support for 128-bit integer numbers.
Added convenience commands like count(where:) for easier programming.

For this round of standard library updates, Swift on Windows and Linux align more closely with iOS/macOS, implementing new libraries using Swift itself.
Arm64 support on Windows and additional packages for Debian, Fedora, and Ubuntu 24.04 on Linux, along with an easier way to download the static SDK for Linux, like building Docker images.

TLDR: Apple’s Swift language project unveils version 6.0 with improved concurrency, typed throws, better C++ integration, embedded usage, and enhanced standard library updates for Windows and Linux systems.
