1. 原因分析

1）cocoapods太老，不支持，需要升级cocoapods
2）因为cocoapods太老，支持的Quick版本太老

2.解决办法

解决办法：升级cocoapods后，升级Quick

3.如何确定自己pod的第三方控件有问题

https://github.com/Quick/Quick/issues/731
Try the following:

1. Open xcode schemes list.
2. Tick Nimble and Quick with “show” and close.
3. Select Nimble as a scheme and build (cmd + b)
4. Select Quick as a scheme and build (cmd + b)
5. Change scheme back to your app scheme and see if the error is gone and autocompletion works.

操作步骤：

勾选Nimble Quick 然后选择Nimble、Quick进行编译，通过就没问题，没通过，肯定有问题

如何升级cocoapods

参考链接：
https://www.jianshu.com/p/8b61b421dd76
https://www.jianshu.com/p/7e166bec1b56（较靠谱，卸载那一步）

1）gem list –local | grep cocoapods

2）卸载cocoapods

使用命令逐个删除
$ sudo gem uninstall cocoapods-core
$ sudo gem uninstall cocoapods-deintegrate
…

3）安装新版

$ sudo gem install cocoapods 差不多过个几十秒吧
$ pod setup （关键，一定要进行这一步）
然后会有提醒结果：
CocoaPods 1.4.0 is available.
To update use: gem install cocoapods

4）gem install cocoapods 进行完了这一步之后，才能真正的升级完pod

5) pod –version 查看是否升级了
