Learning Swift, sans Xcode

Say you are learning Swift. And like a good fanboi, the first thing you do is update to the latest and greatest because that’s like what you do when you are a nerd.

But you live in Osh, Kyrgyzstan. You have bitchin’ FTTH from Unilink, but access outside of Kyrgyzstan is still limited by the great firewall that Putin has put up in Moscow or whatever. I don’t know, but it’s slow as hell.

So you want to learn Swift, but Xcode is out of commission because it is upgrading. Well, sort of out of commission. It gives an “I’m upgrading” message, but it is still there in /Applications/Xcode.app.

So you can use this script to call Swift as an interpreter, and then you can learn Swift in Emacs, where you should be programming anyway, YOU FOOL.

#!/bin/sh

xc="/Applications/Xcode.app/Contents/"

$xc/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift \
 -frontend \
 -interpret $1 \
 -target x86_64-apple-darwin15.2.0 \
 -enable-objc-interop \
 -sdk $xc/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk \
 -module-name `basename $1 .m`
rc=$?

echo
echo "Exit code: $rc"
