原因

Xcode10使用了新的task的build方式，之前在做私有庫的時候沒有很嚴格，將私有庫的Info.plist檔案也放在了Pod-Spec檔案中引入到工程了，所以新的打包方式將這些Info.plist和主工程的都copy到相同的地方發生了報錯。

解決方案

原因知道了那麼解決方案就很清楚--將這些Info.plist從工程中刪除掉：

1. 修改私有庫的spec檔案，然後升級每一個私有庫。這是最正確的但是有很多時候專案私有庫很多，依賴很複雜，升級一次成本很高。
2. 既然使用了Pod那就在Pod指令碼上想想辦法，很顯然可有在Podfile的Hook方法，post_install裡面講pod庫的Info.plist引用刪除掉，程式碼如下：

### 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
