New Build System會對構(gòu)建中的元素循環(huán)進(jìn)行嚴(yán)格的檢查，避免不必要的重建，這個也是錯誤出現(xiàn)的原因。

錯誤發(fā)生的兩種普遍形式：

1、info.plist

錯誤信息

Multiple commands produce '/Users/tjsoft/Library/Developer/Xcode/DerivedData/TYKYTwoLearnOneDo-amcfzswumxdotlgjwdslugmywxch/Build/Products/Debug-iphoneos/TYKYTwoLearnOneDo.app/Info.plist':

1) Target 'TYKYTwoLearnOneDo' (project 'TYKYTwoLearnOneDo') has copy command from '/Users/tjsoft/TYKY /黨建/黔紀(jì)/QianJiDangJian_iOS/TYKYTwoLearnOneDo/Info.plist' to '/Users/tjsoft/Library/Developer/Xcode/DerivedData/TYKYTwoLearnOneDo-amcfzswumxdotlgjwdslugmywxch/Build/Products/Debug-iphoneos/TYKYTwoLearnOneDo.app/Info.plist'

2) Target 'TYKYTwoLearnOneDo' (project 'TYKYTwoLearnOneDo') has process command with output '/Users/tjsoft/Library/Developer/Xcode/DerivedData/TYKYTwoLearnOneDo-amcfzswumxdotlgjwdslugmywxch/Build/Products/Debug-iphoneos/TYKYTwoLearnOneDo.app/Info.plist'

2、Copy Pods Resources

錯誤信息

Multiple commands produce '/Users/tjsoft/Library/Developer/Xcode/DerivedData/TYKYTwoLearnOneDo-amcfzswumxdotlgjwdslugmywxch/Build/Products/Debug-iphoneos/TYKYTwoLearnOneDo.app':

1) Target 'TYKYTwoLearnOneDo' has create directory command with output '/Users/tjsoft/Library/Developer/Xcode/DerivedData/TYKYTwoLearnOneDo-amcfzswumxdotlgjwdslugmywxch/Build/Products/Debug-iphoneos/TYKYTwoLearnOneDo.app'

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

解決方法可以有兩種，一種是不使用New Build System，在File > Project/Workspace Settings中的Share Project/Workspace Settings 里build system 將New Build System(Default)切換成Legacy build system。

其次是根據(jù)出錯信息，在新創(chuàng)建系統(tǒng)模式下，去除多余的引用重建。

Info.plist

在 target -> Build phase > Copy Bundle Resource 中找到info.plist，移除

Copy Pods Resources

在 target -> Build phase > Copy Pods Resources -> Output Files，移除${TARGET_BUILD_DIR}/${UNLOCALIZED_RESOURCES_FOLDER_PATH}
