如何在终端中使用Swift

像这样

export PATH=$PATH:/Applications/Xcode6-Beta.app/Contents/DeveloperToolchains/XcodeDefault.xctoolchain/usr/bin

但我发现这篇文章How to use swift in your terminal

哪一个更好？

$xcrun swift -v -o test test.swift

但请注意,swift库是从/Applications/Xcode6-Beta/…/swift/macosx加载的(通过@rpath),因此二进制文件不能在另一个系统上运行,除非它在同一个地方安装了相同版本的Xcode .除非您想要进行大量复制/ install_name_tool调用以对其进行排序…
