Question

我是Xcode的新Swift程序员，我不明白为什么会出现这种错误。

错误：

主题1：EXC_BAD_INSTRUCTION（代码= EXC_I386_INVOP，子代码= 0x0）

它发生在使用

的for-in循环中的XMLParser.swift中

Ss.append(Scene(title: e["name"].text!, imageStr: e["image"].text!, info: e["info"].text!, isEnabled: Bool(e["isEnabled"].text!)!, action: e["action"].text!, id: e.attributes["id"]!)!)
