Swift 3.0 發布流程 (英文)

This post describes the goals, release process, and estimated schedule for Swift 3.0.

Swift 3.0 is a major release that is not source-compatible with Swift 2.2. It contains fundamental changes to the language and Swift Standard Library. A comprehensive list of implemented changes for Swift 3.0 can be found on the Swift evolution site.

Swift 3.0 is also the first release to include the Swift Package Manager. While the Swift Package Manager is still early in its development, it supports the development and distribution of cross-platform Swift packages. The Swift Package Manager will be available on both Darwin and Linux.

For Linux, Swift 3 will also be the first release to contain the Swift Core Libraries.

Swift 3.0 is expected to be released sometime in late 2016. In addition to its release, Swift 3.0 will ship in a future version of Xcode.
