在这个脚本中显示了文本域，但是每次击键后它都重置为“播放器1”。2有人能帮助我吗？

import SwiftUI

class Player: ObservableObject {
    @Published var playerData = "player 1"
}

let player = Player()

struct ContentView: View {
    @ObservedObject var player: Player
    
    var body: some View {
        TextField("player", text: $player.playerData)
    }  
}

已尝试使用其他代码，但未成功。

按热度按时间

class Player: ObservableObject {
    @Published var playerData = "player 1"
    
    static let shared = Player()
}

struct ContentView: View {
    @ObservedObject var player = Player.shared
    
    var body: some View {
        TextField("player", text: $player.playerData)
    }
}

但是，通常模型存储是environmentObjectPlayerStore，并且包含Player模型结构体数组。

将@ObservedObject替换为@StateObject，它应该可以工作
