Ubuntu 14.04 Package for Open Source Swift 2.2


Ubuntu 15.10 and 14.04 instructions are now available here!

Quick and easy instructions for installing Open Source Swift 2.2 on Ubuntu 14.04 using apt-get.

1. Add the repository key

wget -qO- http://dev.iachieved.it/iachievedit.gpg.key | sudo apt-key add -

2. Add the repository to sources.list

echo "deb http://iachievedit-repos.s3.amazonaws.com/ trusty main" | sudo tee --append /etc/apt/sources.list

3. Run apt-get update

sudo apt-get update

4. Install swift-2.2!

apt-get install swift-2.2

I am currently serving this package off of Amazon S3 so it may take a bit to download. I am looking at whether or not I can afford utilizing CloudFront.

5. Try it out

git clone https://github.com/apple/example-package-dealer
cd example-packager-dealer
swift build

Q. Did Apple build these binaries?
A. No, I built them on my personal server using the instructions I posted here.

Q. What git revisions are included in the build?
A. You can use apt-cache show swift-2.2 to see this information. For example:

# apt-cache show swift-2.2

The source tree is untouched for each build.

Q. Do you test the binaries before you upload them?
A. The Swift build process tests the resulting binaries, and I then do run some basic tests and compile my own applications, but there is currently no separate exhaustive test suite.

Q. Are you releasing builds on a set schedule?
A. Not really, though I may try to stay in sync with the releases from Apple. The idea was to get something out for folks to experiment with and start coding Swift on Linux.

Q. Where is everything installed?
A. Everything gets put in /usr, just like installing clang, gcc, etc.

Q. How do I decipher the package version number?
A. This was my first take on what I thought should be an appropriate package version number. Breaking it down, 2.2-0ubuntu3~trusty1 should be:

  • 2.2 is the version of Swift that is packaged
  • -0ubuntu3 indicates that this is the 3rd package for Ubuntu, with the 0 indicating that there is no upstream Debian package upon which this package was based
  • ~trusty1 indicates that this package is for Trusty Tahr

I think I got that right, but if you feel otherwise please do drop me a line at support@iachieved.it.

How Does This Work?

I used these awesome instructions on how to host a Debian package repository on Amazon S3. I tried to set up a Launchpad PPA, but quite frankly, got tired of trying to wade through all the metadata required to put together a simple package. I’m sure for hosting distribution repositories it’s all required, but for this it felt like overkill. The folks that develop fpm also have some choice things to say about it.

In addition I’ll be submitting the other bits on how to package and upload to Github.
