swift - 崩溃 - EXC_BAD_ACCESS KERN_INVALID_ADDRESS 专用 _VariantDictionaryBuffer.nativeUpdateValue(_:forKey:)

Question

我发生了崩溃，但我不确定是什么原因造成的。

我使用 Twilio 框架，一切正常，但我遇到了一个奇怪的 prod 崩溃，我看起来像是一个与 Dictionary 相关的问题：

票务管理器功能：

func getAndJoinDialog(roomId : String,onSuesscs: @escaping (() -> Void),onFaild: @escaping (()-> Void)) {
    if let channel = self.getDialog(roomId) {
        self.addDialog(channel)
        self.joinDialogWithBlock(channel, successBlock: onSuesscs, failBlock: { (_) in
            onFaild()
        })
        return
    }
    self.chat?.channelsList()?.channel(withSidOrUniqueName: roomId, completion: { (result, channel) in
        if result.isSuccessful() && channel != nil{
            self.addDialog(channel!)
            self.joinDialogWithBlock(channel!, successBlock: onSuesscs, failBlock: { (_) in
                onFaild()
            })
        }else {
            DDLogError("getAndJoinDialog error: \(String(describing: result.error))")
            onFaild()
        }
    })
} <- **Crash on this line**

添加对话框功能

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

我不确定是什么导致了这次崩溃
