Swift Presentation构建并展示Swift的Cocoa框架

快速演示这个项目生成并部署了一个用Swift构建的Cocoa框架，它可以从命令行REPL或从Xcode Playground使用，如下所示：

import PresentationKit

let pres = Presentation(name: \"Tao of Swift\")

let currentDemo = pres[\"sets\"]

if let demo = currentDemo {

    let URL = demo.URL

    let tweet = demo.tweet

    let source = demo.sourceCode

    demo.explain()

    demo.copyCode()

    demo.show()

}

// The Presentation class can be iterated for demo
