[iOS问题]- Error: Multiple commands produce 解决办法！

错误发生的两种普遍形式：

1、info.plist

错误信息

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 /党建/黔纪/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

错误信息

Multiple commands produce '/Users/satoshi_uma/Library/Developer/Xcode/DerivedData/Hospital-bztfekjhqhihnxaarhkecyjfvdyc/Build/Products/Debug-iphoneos/***.app/NIMKitEmoticon.bundle':
1) Target 'Hospital' (project 'Hospital') has copy command from '/Users/satoshi_uma/Desktop/华为版本/ys-app-develop/ios/Hospital/Resource/NIMKitEmoticon.bundle' to '/Users/satoshi_uma/Library/Developer/Xcode/DerivedData/Hospital-bztfekjhqhihnxaarhkecyjfvdyc/Build/Products/Debug-iphoneos/***.app/NIMKitEmoticon.bundle'
2) That command depends on command in Target 'Hospital' (project 'Hospital'): script phase “[CP] Copy Pods Resources”

解决方法可以有两种，一种是不使用New Build System，在File > Project/Workspace Settings中的Share Project/Workspace Settings 里build system 将New Build System(Default)切换成Legacy build system。

File -> WorksSpace Setting

其次是根据出错信息，在新创建系统模式下，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}
