在swift 中引入AFNetworking时遇到的问题

刚开始学习swift，什么都不明白，希望在项目中引用AFNworking，访问网络服务，不知道如何使用，先是直接把文件copy到项目中完全没有用，找了一些 swift调用C 和object_c的例子，试着是要加一个桥接文件，可以成功的调用，但是没有正常的提示符。

在群中问了一下，有人提示 cocoapods，好搜索了一下这个东本，发现了：

CocoaPods安装和使用教程

http://code4app.com/article/cocoapods-install-usage

这个写的非常好，按其中的操作来做，但遇到这样的问题：

[!] /usr/bin/git clone 'https://github.com/CocoaPods/Specs.git' master --depth=1

xcrun: error: active developer path ("/Volumes/Xcode/Xcode.app/Contents/Developer") does not exist, use xcode-select to change

没有文件目录，找了好多例子，都是一句话：

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer 即可解决。




但我是执行的时候，还是报错误，

xcode-select: error: invalid developer directory '/Applications/Xcode.app/Contents/Developer'

没有目录，又找找，发现问题是出现在Xcode.app这里，我用的是Xcode6-Beta.app修改一下命令如下

sudo xcode-select -switch /Applications/Xcode6-Beta.app/Contents/Developer

成功了：

usertekiMacBook-Air:~ user$ sudo xcode-select -switch /Applications/Xcode6-Beta.app/Contents/Developer

usertekiMacBook-Air:~ user$ pod search AFNetworking

Setting up CocoaPods master repo

Setup completed (read-only access)

再执行

pod search AFNetworking

看到了正常的结果：
