ios - 在对象数组的字典中应用过滤器

Question

我有一类名为“EpisodeInfoData”的属性

class EpisodeInfoData {
    var episodeId = ""
    var episodeName = ""
}

我将这些类的对象存储到一个字典中，该字典的第一个元素是“String”，另一个元素是“EpisodeInfoData”类对象的数组

var episodes    = Dictionary<String, [EpisodeInfoData]>()

let infoObj1 = EpisodeInfoData()
infoObj1.episodeId           = "1"
infoObj1.episodeName         = "one"

let infoObj2 = EpisodeInfoData()
infoObj2.episodeId           = "2"
infoObj2.episodeName         = "two"

let infoObj3 = EpisodeInfoData()
infoObj3.episodeId           = "3"
infoObj3.episodeName         = "three"

let infoObj4 = EpisodeInfoData()
infoObj4.episodeId           = "4"
infoObj4.episodeName         = "four"

let infoObj5 = EpisodeInfoData()
infoObj5.episodeId           = "5"
infoObj5.episodeName         = "five"

let infoObj6 = EpisodeInfoData()
infoObj6.episodeId           = "6"
infoObj6.episodeName         = "six"

let infoObj7 = EpisodeInfoData()
infoObj7.episodeId           = "7"
infoObj7.episodeName         = "seven"

let infoObj8 = EpisodeInfoData()
infoObj8.episodeId           = "8"
infoObj8.episodeName         = "eight"

episodes["season1"] = [infoObj1,infoObj2,infoObj3,infoObj4]
episodes["season2"] = [infoObj5,infoObj6,infoObj7,infoObj8]

我想在剧集名称为“八”的“剧集”词典中获取季节名称。我已尝试对其应用过滤器，但它不起作用。

任何人都可以建议我在不使用过滤器的情况下使用过滤器找到结果。

提前谢谢你

不得不添加另一个答案，感谢那些在没有真正帮助的情况下投票的人。

试试这个

if let episode = (episodes.filter { $0.1.contains { $0.episodeName == "eight" } }).first {
    print(episode.0) // season2
}
