本文详细记录了从Swift 1.2版本项目升级至Swift 2.0并集成iOS 9环境时，遇到的CocoaPods安装错误及解决过程。从错误日志分析入手，逐步排查并成功解决依赖库Alamofire升级时的配置问题。

前言：今天一时兴起，想接着做之前做的一个Swift的小项目有，打开xcode发现已经是7.0.1的版本号了，集成了iOS9和swift2.0，可想而知，之前基于swift1.2版本的代码又需要修改才能编译通过了哦。

不光是自己写的代码，连引入的第三方库也需要升级，比如网络请求神器Alamofire，在github上搜索Alamofire，看到大神已经更新的版本支持最新的swift和xcode了，果然是大神。按照github文档中的

pod 'Alamofire', '~> 2.0'

加入到Podfile中，执行

pod install --verbose --no-repo-update

果然，报错了，唉。。。程序员就是要和无限的bugs做斗争，起来找原因了。。。
