Xcode 8 beta 6 AnyObject Swift 3 更改

Question

Xcode beta 6 改变了一些 Swift 语言

Since ‘id’ now imports as ‘Any’ rather than ‘AnyObject’, you may see errors where you were previously performing dynamic lookup on ‘AnyObject’.

我已经尝试过在执行动态查找之前显式转换为 AnyObject 或强制转换为特定对象类型的修复程序

但我不确定我做对了 - 有人可以帮忙吗，这里是 Beta 5 的原始工作代码

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! SpecialCell
        let maindata = values[(indexPath as NSIndexPath).row]
        cell.name.text = maindata["name"] as? String
        cell.id.text = maindata["id"] as? String
        //team_id.text = maindata["team_id"] as? String

        return cell
    }

Answer 1

根据 beta 6 发行说明，您必须(桥接)转换到 AnyObject

cell.name.text = (maindata["name"] as AnyObject) as? String

或强制施放

cell.name.text = maindata["name"] as! String

这是比普通字典更喜欢具有不同属性类型的自定义类/结构的另一个原因。
