  <div class="entry-content"><p>Swift类似脚本语言的高级语法特性，让Swift语言使用起来很直观，很符合人的直觉，整体感觉很简洁很舒服。使用不同编程语言的程序员都能找到熟悉的感觉，这种亲切感必将吸引更多的开发者。<br>
本文总结Swift中需要注意的语法细节，完整的语法说明参考苹果的官方文档<a href="https://developer.apple.com/library/prerelease/ios/documentation/Swift/Conceptual/Swift_Programming_Language/">The Swift Programming Language</a>。</p>

  <div class="entry-content"><p>Swift中引入了很多高级语言的特性，如闭包、命名空间、泛型、强类型（同时拒绝阴式类型转换）、多个返回值（元组）等等，这些高级的语法糖用好了可以极大提升工作效率，用不好也是语法坑。<br>
我们先体验一下Swift的糖衣炮弹。</p>

  <div class="entry-content"><p>Ninja，中文“忍者”的意思。这里说到的Ninja是一个<a href="https://github.com/martine/ninja">专注于速度的构建系统</a>，正式的版本可以从<a href="https://github.com/martine/ninja/releases">这里</a>下载。写本文时的版本是1.4.0。</p>

<p>最初遇到Ninja是在编译Webrtc的时候，记得以前还是感觉乱乱的<a href="https://code.google.com/p/gyp/">gyp</a>，不知什么时候换成陌生的Ninja了。当时匆匆解决了编译问题，没仔细看Ninja的细节，后来在看aosabook的<a href="http://aosabook.org/en/intro1.html">《The Architecture of Open Source Applications》</a>、<a href="http://aosabook.org/en/posa/introduction.html">《The Performance of Open Source Applications》</a>系列的书时，又提到了Ninja，不由得想用用试试看了。</p>
