刚开始接触swift，想着在mac上用 swift REPL，敲一些简单的语法，不需要一句简单的print用xcode还要编译。结果按照网上和书本的相关教程，不管怎样都无法正常使用swift REPL，尝试过stack overflow上的一些解决方案，始终无法解决，求使用过的有经验者帮帮忙。
osx version：10.10.5
xcode version：7.2.1
先转换xcode目录
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer再运行xcrun swift或者swift
$ xcrun swift

网上找来找去也就这两种配置，在我mac上都无法使用，求解决方法。
我的问题，更新版本便可解决，至于具体原因在哪儿，我就不清楚了，因为没时间去深究，能用了就好。所以有遇到和我问题类似情况的朋友们，不妨先升级，再试试看，如果不行再找其他方案。
