问题
最近在 Xcode 11 上使用 pod 碰到一个问题，Assets.car 被生成多次。错误信息如下：
Multiple commands produce '/Users/xxx/Library/Developer/Xcode/DerivedData/xxx/Build/Products/Debug-iphonesimulator/xxx.app/Assets.car':
1) Target 'xxx' (project 'xxx') has compile command with input '/Users/xxx/projects/libs/xxx/xxx/Example/xxx/Images.xcassets'
2) That command depends on command in Target 'xxx' (project 'xxx'): script phase “[CP] Copy Pods Resources”
解决方法如下：
在 Podfile 文件中最前面添加以下代码解决：
install! 'cocoapods', :disable_input_output_paths => true
