Swift 是一种新的编程语言，用于编写 iOS 和 OS X 应用。Swift 结合了 C 和 Objective-C 的优点并且不受C的兼容性的限制。Swift 使用安全的编程模式并添加了很多新特性，这将使编程更简单，扩展性更强，也更有趣。除此之外，Swift 还支持人见人爱的 Cocoa 和 Cocoa Touch 框架。拥有了这些特性，Swift将重新定义软件开发。

默认值参数的外部参数名（External Names for Parameters with Default Values）
在大多数情况下，给带默认值的参数起一个外部参数名是很有用的。这样可以保证当函数被调用且带默认值的参数被提供值时，实参的意图是明显的。
为了使定义外部参数名更加简单，当你未给带默认值的参数提供外部参数名时，Swift会自动提供外部名字。此时外部参数名与局部名字是一样的，就像你已经在局部参数名前写了井号（#）一样。

方法(Methods)
方法是与某些特定类型相关联的功能/函数。类、结构体、枚举都可以定义实例方法；实例方法为指定类型的实例封装了特定的任务与功能。类、结构体、枚举也可以定义类(型)方法(type itself)；类型方法与类型自身相关联。类型方法与Objective-C中的类方法(class methods)相似。

下标可以定义在类(Class)、结构体(structures)和枚举(enumerations)这些目标中，可以认为是访问对象、集合或序列的快捷方式。举例来说，用下标访问一个数组(Array)实例中的元素可以这样写 someArray[index] ，访问字典(Dictionary)实例中的元素可以这样写 someDictionary[key]，而不需要再调用实例的某个方法来获得元素的值。

一个类可以继承另一个类的方法，属性和其它特性。当一个类继承其它类，继承类叫子类，被继承类叫超类（或父类）。在Swift中，继承是区分「类」与其它类型的一个基本特征。

Optional Chaining
可选链（Optional Chaining）是一种可以请求和调用属性、方法及子脚本的过程，它的自判断性体现于请求或调用的目标当前可能为空（nil）。如果自判断的目标有值，那么调用就会成功；相反，如果选择的目标为空（nil），则这种调用将返回空（nil）。多次请求或调用可以被链接在一起形成一个链，如果任何一个节点为空（nil）将导致整个链失效。

特性
特性提供了关于声明和类型的更多信息。在Swift中有两类特性，用于修饰声明的以及用于修饰类型的。例如，required特性，当应用于一个类的指定或便利初始化器声明时，表明它的每个子类都必须实现那个初始化器。再比如noreturn特性，当应用于函数或方法类型时，表明该函数或方法不会返回到它的调用者。

在 Swift 中，有两种类型的语句：简单语句和控制流语句。简单语句是最常见的，用于构造表达式和声明。控制流语句则用于控制程序执行的流程，Swift 中有三种类型的控制流语句：循环语句、分支语句和控制传递语句。

这个例子中定义了两个简单的数学函数：`addTwoInts`和`multiplyTwoInts`。这两个函数都传入两个`Int`类型， 返回一个合适的`Int`值。
这两个函数的类型是`(Int, Int) -> Int`，可以读作“这个函数类型，它有两个`Int`型的参数并返回一个`Int`型的值。”。

这个函数的类型是：`() -> ()`，或者叫“没有参数，并返回`Void`类型的函数。”。没有指定返回类型的函数总返回 `Void`。在Swift中，`Void`与空的元组是一样的。

上面这个例子中计算出从`currentValue`逐渐接近到`0`是需要向正数走还是向负数走。`currentValue`的初始值是`3`，这意味着`currentValue > 0`是真的（`true`），这将使得`chooseStepFunction`返回`stepBackward`函数。一个指向返回的函数的引用保存在了`moveNearerToZero`常量中。
现在，`moveNearerToZero`指向了正确的函数，它可以被用来数到`0`：
