Question

我正在构建一个有桌子的应用，并且我试图删除行。首次弹出此错误时，我认为它源自我的视图控制器。我查看了StackOverflow，我发现了与我相似的问题，但没有一个解决方案有效。这是代码：

override func tableView(_ tableView: UITableView,
                        commit editingStyle: UITableViewCellEditingStyle,
                        forRowAt indexPath: IndexPath) {
    if editingStyle == .delete {
        let monsterDude = monsterSections[indexPath.section].monsters[indexPath.row]
        verifyDelete(monsterDude.name, {
            (action) -> Void in
            self.growler.removeMonster(monsterDude)
            self.tableView.deleteRows(at: [indexPath],
                                      with: .automatic)
        })
    }
}

我尝试了很多不同的东西 - 从使用reloadData进行测试来重写我的numberOfSections方法 - 所以现在我认为它必须是我的removeMonster方法本身的问题（实际上删除了密钥和我用来存储我所有怪物的字典中的价值。这是班级：

func removeMonster(_ name: String, _ monsterType: MonsterType, _ strength: Strength) {
    let monsterMan = Monster(name, monsterType, strength)
    removeMonster(monsterMan)
}

func removeMonster(_ monsterMan: Monster) {
    monsters.removeValue(forKey: monsterMan.strength)
}

这是我宣布我的字典的方式：

var monsters = Dictionary<Strength, [Monster]>()

以下是错误消息：

如果您有任何明显的错误，请告诉我们！如有必要，我很乐意提供更多信息。我只想删除表格中的内容。谢谢！！
