原因

Xcode10使用了新的task的build方式，之前在做私有库的时候没有很严格，将私有库的Info.plist文件也放在了Pod-Spec文件中引入到工程了，所以新的打包方式将这些Info.plist和主工程的都copy到相同的地方发生了报错。

解决方案

原因知道了那么解决方案就很清楚--将这些Info.plist从工程中删除掉：

1. 修改私有库的spec文件，然后升级每一个私有库。这是最正确的但是有很多时候项目私有库很多，依赖很复杂，升级一次成本很高。
2. 既然使用了Pod那就在Pod脚本上想想办法，很显然可有在Podfile的Hook方法，post_install里面讲pod库的Info.plist引用删除掉，代码如下：

### HOOK POST
post_install do |installer|
    installer.pods_project.native_targets.each do |natviTarget|
        natviTarget.build_phases.each do |buildPhase|
            info_plist_ref = buildPhase.files.find { |f| f.file_ref.to_s == "Info.plist" }
            if info_plist_ref
               buildPhase.remove_reference(info_plist_ref)
            end
        end
    end
end
