Swift 崩溃-EXC\u错误\u访问内核\u无效\u地址专用\u VariantActionAryBuffer.nativeUpdateValue（\uU:forKey:）

我撞车了，但我不确定是什么原因造成的

我使用了Twilio框架，一切都很好，但我遇到了一个奇怪的prod崩溃 我觉得这是一个与词典相关的问题：

TicketManager函数：

    if let channel = self.getDialog(roomId) {
        self.addDialog(channel)

        return

    })
} <- **Crash on this line**

我不确定是什么原因导致了这次崩溃

我建议您将此作为问题在GitHub上打开。SDK团队经常检查repo和答案或帮助。你确定此崩溃来自Twilio吗？在堆栈跟踪中，看起来崩溃来自TestApp-（我的应用程序）你可以使用空字符串作为字典键吗？是的，我现在在操场上检查，你可以在字典中输入空字符串。对不起，我不太擅长iOS，我不知道这里发生了什么。如果Twilio聊天有问题，我会在GitHub上提出。如果没有，你可以希望其他人能在这里提供帮助。

func addDialog(_ dialog:TCHChannel)
{
    self.dialogs[dialog.sid ?? ""] = dialog
}
