Xcode 11.2上传app store 失败

对app进行app store验证时报错。

ERROR ITMS-90534: "Invalid Toolchain. Your app was built with an unsupported version of Xcode or SDK.

If you are using an Xcode beta version to test your app, make sure you are using the latest supported version.

WARNING ITMS-90703: "Deprecated Xcode Build. Due to resolved app archives issues, we have deprecated Xcode 11.2 on November 5, 2019. Download Xcode 11.2.1 or newer, rebuild your app and resubmit."

在stack overFlow中找到了相同问题，感觉是Xcode11.2的bug.

解决方法：下载Xcode 11.2.1后打包提交成功。
碰到问题： 下载Xcode 11.2.1安装包后无法解压安装，使用Mac自带的解压工具app，其它解压工具无法解压苹果压缩包
打开解压工具：进入/System/Library/CoreServices/Applications文件夹，有个归档实用工具，双击打开。
