我正在尝试将 Alamofire 更新到 4.0 版。当我运行 carthage update 时，我在构建 Alamofire 方案时遇到了很多错误。看起来文件没有更新为 Swift 3.0 语法。我做错了什么？从终端登录：

....... and many others

我使用的是迦太基 0.18 版。我尝试删除 carthage Build 和 Checkout 文件夹。我已将 Xcode 8 版本设置为默认值。目前没有任何运气。

标签： alamofire swift3 xcode8 carthage

【解决方案1】：

问题是在终端默认Xcode仍然是7。我通过命令检查了它：

xcodebuild -version

Xcode 7.3
Build version 7D175

在系统中看起来默认是 Xcode 8.0 但不是在终端中。所以我使用命令：

sudo xcode-select -switch /Applications/Xcode\ 8.app/

现在它开始工作了。
