构建
OS X
记事本应用的
前期准备工作
第一部分介绍了
Apple
开发者计划，在
Apple
平台中做开发所需的工具，以及
Swift
语
言基础。现在，我们要开始构建真正的应用了！
从本章开始，我们将构建一个记事本应用，名为
Notes
。这是
Mac
应用，用于编写笔记，
除了文本之外还能添加其他附件，如图像、位置、视频、音频、联系人等。我们将在第
三部分为
Notes
开发一个运行在
iOS
平台中的对应应用。
本章不会编写任何代码，但是依然重要。我们将使用
Xcode
创建一个真实可用的
OS X
应用（不过还没什么用），做好前期准备。
本章要做的前期准备工作对大多数使用
Swift
开发的
OS X
和
iOS
应用都有用。使用
Xcode
和
Swift
为
Apple
平台开发应用最大的优势是，很多工作都为我们做好了。就在
一两年前，本章所做的前期准备工作还要编写大量代码才能完成。
即便你只想学习使用
Swift
开发
iOS
应用，我们还是建议你阅读讲解如何开发
OS X
应
用的这几章（只有四章而已）。这几章能让你更好地理解如何使用
Swift
和
Xcode
构建
应用，这样在第三部分开始构建
iOS
应用时便能得心应手。

设计这个
OS X
记事本应用
准备着手构建这个应用时，我们只知道自己想构建一个支持添加附件的记事本应用。为
了理清整个过程，我们画了几张线框图。

线框图是草图，示意想构建的应用。在纸上（电子纸或真正的纸）画出想法比直接
动手实现应用快得多，而且画出想法的过程有助于理清思路。
我们通常使用
