:-1: Multiple commands produce '/Users/Admin/Library/Developer/Xcode/DerivedData/UniversalApp-agqgvsfsncufvjfgxpbofsiacwde/Build/Products/Debug-iphonesimulator/UniversalApp.app':
1) Target 'UniversalApp' has create directory command with output '/Users/Admin/Library/Developer/Xcode/DerivedData/UniversalApp-agqgvsfsncufvjfgxpbofsiacwde/Build/Products/Debug-iphonesimulator/UniversalApp.app'
2) That command depends on command in Target 'UniversalApp': script phase “[CP] Copy Pods Resources”

解决步骤：
Xcode-> File->Project/Workspace settings.
修改 the build system 为 Legacy Build system.
使用这种方法没有报这个错误了
