Swift 中字符串到枚举的映射

一篇关于 Swift 中字符串到枚举的映射的文章，并添加案例代码。

swift
enum MusicGenre {
    case rock
    case pop
    case hipHop
}

swift
let genreMapping: [String: MusicGenre] = [
    "Rock": .rock,
    "Pop": .pop,
    "Hip Hop": .hipHop
]

swift
let selectedGenre = "Pop"
if let genre = genreMapping[selectedGenre] {
    print("您选择了\(selectedGenre)音乐类型，对应的枚举值为\(genre)")
} else {
    print("无法找到与\(selectedGenre)对应的枚举值")
}
