swift - "Duplicate keys of type ... were found in a Dictionary "什么时候没有字典？

Question

我对 Swift 很陌生，我刚刚遇到了一个我找不到解决方案的错误。我目前正在开发一个游戏(Boggle，为了好奇)，我想更新算法找到的单词列表。
我创建了一个结构来保存每个单词及其得分:

struct ScoredWord: Comparable, Identifiable{
let word: String
var points: Int = 0
let id: UUID

init(word: String){
    self.id = UUID()
    self.word = word
    self.points = self.defineScore(word: word)
}

static func < (lhs: ScoredWord, rhs: ScoredWord) -> Bool {}

static func == (lhs: ScoredWord, rhs: ScoredWord) -> Bool {}

func hash(into hasher: inout Hasher) {

private func defineScore(word: String) -> Int{}

(我删除了 func 的内容，因为它对你没用)
算法完成后，我有一个简单的循环，为找到的每个单词创建一个结构并将其存储在@Published 的数组中以供显示

let foundWords = solver.findValidWords()
    
for found in foundWords {
    wordList.append(ScoredWord(word: found))
}

在我看来，数组是这样使用的:

 List(wordListViewModel.wordList, id: \.self) { // 1 Word list
     Text( $0.word )
     Spacer()
     Text("\( $0.points )")
 }

当我运行所有这些时，我得到的错误是:

Fatal error: Duplicate keys of type 'ScoredWord' were found in a Dictionary. 
This usually means either that the type violates Hashable's requirements, or
that members of such a dictionary were mutated after insertion.

我找到了 this post关于相同的错误，其中评论指出错误将来自列表显示不够快并且 ID 混淆，但没有关于如何修复它......
任何的想法？

Answer 1

我认为您没有完全符合 Hashable Protocol
关注 func hash(into hasher: inout Hasher)你缺少的功能
