At WWDC 2025, several new frameworks and APIs were introduced for macOS and Swift. Here are the highlights:

macOS

  • Liquid Glass Design: A new design system called Liquid Glass was introduced, which brings a new depth, fluidity, and dynamism to apps. This design is consistent across macOS and other Apple platforms, allowing developers to refresh and modernize their app designs (Platforms State of the Union).
  • Terminal Updates: The Terminal app on macOS received a fresh look with 24-bit color, new themes inspired by Liquid Glass, and support for Powerline fonts (Platforms State of the Union).

Swift

  • Swift 6.2: This version modernizes more of Foundation's API surface and introduces new APIs to streamline everyday programming tasks. It also includes a new package for launching subprocesses, enhancing scripting capabilities (What’s new in Swift).
  • Strict Memory Safety: A new feature in Swift 6.2 called Strict Memory Safety requires explicit acknowledgment of unsafe API usage in source code, enhancing security (What’s new in Swift).
  • Embedded Swift: Swift 6.2 expands support for Embedded Swift, allowing developers to write code for constrained environments like firmware for embedded devices (What’s new in Swift).
  • WebAssembly Support: Swift 6.2 adds official support for WebAssembly, enabling developers to build applications for the browser or other runtimes (What’s new in Swift).

These updates reflect Apple's continued focus on enhancing developer tools and frameworks to create more powerful and efficient applications across their platforms.
