升級xcode 10.0之后項目出了許多的紅色錯誤

報這個錯誤就是去tagets? 里Build Phases下 [CP]copy pods Resources 刪除下面

然后又會報錯 ld: library not found for -lstdc++.6.0.9（xcode升級之后這些庫不存在，項目里添加的這庫要移除）

1>在TARGETS? ---->General ------>Linked Frameworks and Libraries 下移除libstdc++.6.0.9.tdb庫

2>在TARGETS? ---->Build Settings ------>Other Linker Flages 下移除libstdc++.6.0.9.tdb這個庫的標識鏈接

如果依賴c++6.0.9的SDK是第三方SDK，需要聯(lián)系第三方，等待第三方更新

如果是自己的文件引用了c++，請?zhí)鎿Q對c++庫的使用，重新編譯。

同時還會出現(xiàn)其他的問題，僅供參考

升級完Xcode，編輯運行的時候發(fā)現(xiàn)報了一些錯誤（如下）：

1) Target 'xxx' has create directory command with output '/Users/xx/Library/Developer/Xcode/DerivedData/xxx-enekjocpeavqtedhdmtdevxeaemj/Build/Products/Debug-iphonesimulator/xxx.app'

2) That command depends on command in Target 'xxx': script phase “[CP] Copy Pods Resources”
