我很想使用Carthage来安装Alamofire和SwiftJSON，但我无法使其正常工作。每次构建都失败了。
这是我的Cartfile（指向适用于Xcode 6.3的正确分支）：
我很想弄清楚为什么这不起作用，因为我认为Carthage可能非常棒。请注意，除了按照Cartage git repo上的说明进行操作之外，我什么也没有做。只是运行了cartage update，就发生了这种情况。有任何想法吗？
xcode-select路径正确地指向Xcode的beta版本。

这是我的Cartfile（指向适用于Xcode 6.3的正确分支）：
github "Alamofire/Alamofire" "xcode-6.3"
github "SwiftyJSON/SwiftyJSON" "xcode6.3"
Alamofire构建失败并出现如下错误：

xcode-select命令来选择 Xcode 的测试版进行命令行构建？ - Justin Spahr-Summersbrew update？ - Allen
