Xcode10 報錯 target xxx(project 'xxx')has copy command from ‘xxx/xxx’ to ''xxx/xxx.app/COPYING'解決方案

Xcode10預設使用最新的系統，但運作舊APP時候就會報錯

:-1: Multiple commands produce 'xxx/xxx.app/COPYING':

target xxx(project 'xxx')has copy command from ‘xxx/xxx’ to ''xxx/xxx.app/COPYING'

是以，僅需要将xcode改成舊系統就好了。操作如下：

Xcode ->File->Workspace Settings->build System中将New Build System(Default)修改為Legacy Build System重新運作即可。
