在上面的例子中，枚举原始值的类型是`Int`，所以你只需要设置第一个原始值。剩下的原始值会按照顺序赋值。你也可以使用字符串或者浮点数作为枚举的原始值。 在上面的例子中，枚举原始值的类型是`Int`，所以你只需要设置第一个原始值。剩下的原始值会按照顺序赋值。你也可以使用字符串或者浮点数作为枚举的原始值。
使用`toRaw`和`fromRaw`函数来在原始值和枚举值之间进行转换。 使用'rawValue'在原始值和枚举值之间进行转换。
```swift ```swift
if let convertedRank = Rank.fromRaw(3) { if let convertedRank = Rank(rawValue: 3) {
let threeDescription = convertedRank.simpleDescription() let threeDescription = convertedRank.simpleDescription()
} }
``` ```
