Multiple commands produce
1、错误：xx.app
:-1: Multiple commands produce '/Users/user/Library/Developer/Xcode/DerivedData/xxx-gkttrflwrjbhrcfecpzefanisuxz/Build/Products/Debug-iphonesimulator/xx.app':
1)Target 'xxx' has create directory command with output '/Users/user/Library/Developer/Xcode/DerivedData/xxx-gkttrflwrjbhrcfecpzefanisuxz/Build/Products/Debug-iphonesimulator/xx.app'
2)That command depends on command in Target 'xxx': script phase“[CP]Copy Pods Resources”
错误发生在[CP] Copy Pods Resources，且与output有关。
解决方案：根据提示信息，选中对应的target -> Build Phases -> [CP] Copy Pods Resources -> Output Files -> 移除
{UNLOCALIZED_RESOURCES_FOLDER_PATH} -> build
2、错误：Info.plist
