我只是上传了我的swift / xcode项目的更新。
但是，在修订版中，我将我的应用程序视为已废弃的消息：
我们无法检查您的应用，因为它在发布时崩溃了。我们有 附上详细的崩溃日志以帮助解决此问题。
请修改您的应用并在连接到设备时在设备上进行测试 IPv6网络（所有应用程序必须支持IPv6）以确保它将启动 没有崩溃。
我已经在模拟器和物理设备中测试了应用程序并且它运行良好。但在崩溃日志中说：

我如何在那里找到我的问题？
答案 0 :(得分：0)
根据Apple的文档
如果出现意外情况，Swift代码将以此异常类型终止 在运行时遇到条件，例如：
具有零值的非可选类型
失败的强制类型转换
您可能会意外地用nil值解包一个可选项，或者在类型转换中做错了（请参阅此answer）。
对于IPv6兼容性，您可以浏览Apple的documentation。
