Multiple commands produce '/Users/saj/Library/Developer/Xcode/DerivedData

升级XCode10后报以下报错：

Showing All Messages :-1: Multiple commands produce '/Users/saj/Library/Developer/Xcode/DerivedData/xxx-ghytlsyvibsjoihcqyszxpsqfqbt/Build/Products/Debug-iphoneos/xxx.app/Info.plist': 1) Target 'xxx' (project 'xxx') has copy command from '/Users/saj/Down

XCode10编译旧项目狂吃内存的解决办法

打开File---workspace setting...---Build System：选择Legacy Build System。

老项目还是用老的编译系统吧。
