| Because it's an alias, | ||
| the call to `AudioSample.min` actually calls `UInt16.min`, | ||
| which provides an initial value of `0` for the `maxAmplitudeFound` variable. | ||
| `在这里，AudioSample` 被定义为 `UInt16` 的别名。 |

| Conversions between integer and floating-point numeric types must be made explicit: | ||
| 整数和浮点数值类型之间的转换必须明确： |
There was a problem hiding this comment.
explicit 和 explicitly 翻译成显式会不会更好？比如：整数和浮点数类型之间的转换必须显式进行。可以考虑一下。文中一共 17 处涉及这两个单词的翻译，不重复提了
| you'll trigger a runtime error. | ||
| The result is exactly the same as if you write an exclamation point | ||
| to force unwrap a normal optional that doesn't contain a value. | ||
| 如果一个隐式解包的可选值为 `nil`，而你试图访问它的包装值，就会触发运行时错误。 |
| 当 `nil` 表示不可恢复的故障时（如程序员错误或状态损坏）， | ||
| 你可以通过在可选名称的末尾添加感叹号 (`!`) 来访问底层值。 | ||
| 这被称为*强制解包*可选的值。 | ||
| 强制解包一个非 `nil` 值时，结果是其解包值。 |
| > In the `welcomeMessage` example above, no initial value is provided, | ||

| and so this second example passes the type-check. | ||
| Comparisons like `i == 1` are discussed in <doc:BasicOperators>. | ||
| `i == 1` 的比较结果是 `Bool` 类型，因此第二个示例通过了类型检查。 | ||
| 类似 `i == 1` 的比较结果将在<doc:BasicOperators>中讨论。 |
