Swift 6.4 unifies building across Linux, macOS, Windows

Swift Build is now the default engine for the Swift Package Manager

Although Swift serves as Apple's primary language for macOS and iOS application development, the open-source community continues to expand its reach—driving its adoption as a multi-platform language or even a cross-platform one in fields beyond user interface design.

Tuesday’s Swift 6.4 release continued that work. Along with the usual assortment of type shortcuts and async adjustments came word that Swift Build is now the default build engine for the Swift Package Manager.

Synergies have already ensued! The pairing sets the stage for a faster build process. A developer can write a program in Swift and Swift Build will automatically download and install the required dependencies, testing them for compatibility. It then compiles the code into a CPU-specific binary.

The merger also unifies the Swift developer experience regardless of platform.
