對app進行app store驗證時報錯侮叮。
ERROR ITMS-90534: "Invalid Toolchain. Your app was built with an unsupported version of Xcode or SDK.

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中找到了相同問題易阳，感覺是Xcode11.2的bug.
解決方法：下載Xcode 11.2.1后打包提交成功辞友。
碰到問題： 下載Xcode 11.2.1安裝包后無法解壓安裝赦颇，使用Mac自帶的解壓工具app，其它解壓工具無法解壓蘋果壓縮包
打開解壓工具：進入/System/Library/CoreServices/Applications文件夾柴钻，有個歸檔實用工具杜顺，雙擊打開。
