How to use Swift in terminal

Question

I added the path to the Swift environment in Xcode 6_beta.app and used Swift.

Like this

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

But I found this post How to use swift in your terminal

Which one is better?

Answer 1

I use it through xcrun:

$ xcrun swift -v -o test test.swift
Swift version 1.0 (swift-600.0.34.4.5)
Target: x86_64-apple-darwin14.0.0

Please note, however, that fast libraries are loaded (via @rpath) from /Applications/Xcode6-Beta/.../swift/macosx, so the binary will not work on another system unless it receives the same version of Xcode installed in the same place. If you do not want to make many copies / install_name_toolcalls to sort ...

$ otool -l test |fgrep path
