ios – How to avoid duplicated words in an array

I have a question about Swift.

I am making a quiz app to learn English words and I want to display the words in the Word class once the player gets right like the picture attached below. However, as you can see, the list has many duplicated values. How can I fix that? Thank you in advance.List View

@Query var playerInfos: [PlayerInfo1]

List {
      ForEach(Array(Set(playerInfos)), id: \.self) { playerInfo in
             ForEach(Array(Set(playerInfo.correctWords)), id: \.self) { index in
                        Text("\(displayeWord[index].word)")
                            .foregroundColor(.black)
                    }
                }
            }
-----------------
@Model
class PlayerInfo1 {
    var playerScore : Int
    var correctWords : [Int] // store the index of the words that the player gets right 
    
    init(playerScore: Int, correctWords: [Int]) {
        self.playerScore = playerScore
        self.correctWords = correctWords
    }
}
-----------------
class Word : Identifiable {
 
}

let displayeWord : [Word] = [
    Word(word: "Arvo", meaning1: "午後", meaning2: "午前"),
    Word(word: "Bin", meaning1: "ゴミ箱", meaning2: "壺"),
    Word(word: "Runners", meaning1: "スニーカー", meaning2: "走る人"),
