Straight outta Cupertino:

a low-level tool for building high-performance networking applications in Swift. It particularly targets those use-cases where using a “thread-per-connection” model of concurrency is inefficient or untenable. This is a common limitation when building servers that use a large number of relatively low-utilization connections, such as HTTP servers.

Could this be a first step toward Swift-powered servers running all around the globe? Maybe Apple will finally be able to ditch WebObjects… 😉
