error: Multiple commands produce '/Users/maxiansheng/Library/Developer/Xcode/DerivedData/PercussionProject-fwieirugahmmvdeljwhihsvrnmls/Build/Products/Debug-iphonesimulator/PercussionProject.app':
1) Target 'PercussionProject' has create directory command with output '/Users/maxiansheng/Library/Developer/Xcode/DerivedData/PercussionProject-fwieirugahmmvdeljwhihsvrnmls/Build/Products/Debug-iphonesimulator/PercussionProject.app'
2) That command depends on command in Target 'PercussionProject': script phase “[CP] Copy Pods Resources”
分析error内容，错误发生在Copy Pods Resources，而且与output有关，应该是使用了cocoapods导致的，尝试删除该项目target-Copy Pods Resources-Output Files，成功解决问题。
解决步骤：
选中项目target -> Build phase -> Copy Pods Resources -> Output Files -> 移除${TARGET_BUILD_DIR}/${UNLOCALIZED_RESOURCES_FOLDER_PATH} 重新运行即可。

解决1：删除重复的info.plist（删除前请备份好； 右键 show in Finder打开info.plist所在目录）
打开 target > Build pha
