Install Swift on Ubuntu

Requirements

1. Ubuntu 14.04, 16.04, or 16.10

Step 1 - Dependencies

1. Open up terminal
2. Install core deps: sudo apt-get install clang libicu-dev git

Step 1.1 - Ubuntu 14.04 Clang

If you're using Ubuntu 14.04, you need to update to clang 3.6 to prevent errors in the future.

1. Install updated clang: sudo apt-get install clang-3.6
2. Update clang: sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-3.6 100
3. Update clang++: sudo update-alternatives --install /usr/bin/clang++ clang++ /usr/bin/clang++-3.6 100

Step 2 - Install SwiftEnv

I put this application in here because it greatly helps with handling multiple versions of Swift.

1. Make the swiftenv folder: mkdir .swiftenv
2. Clone the repo: git clone https://github.com/kylef/swiftenv ~/.swiftenv
3. Add swiftenv to bash profile #1: echo 'export SWIFTENV_ROOT="$HOME/.swiftenv"' >> ~/.bashrc
4. Add swiftenv to bash profile #2: echo 'export PATH="$SWIFTENV_ROOT/bin:$PATH"' >> ~/.bashrc
5. Add swiftenv to bash profile #3: echo 'eval "$(swiftenv init -)"' >> ~/.bashrc
6. Restart the terminal, or run source ~/.bashrc

Step 3 - Install Swift

Follow the table to know what value to insert in the link below

	Ubuntu 14.04	Ubuntu 16.04	Ubuntu 16.10
#1	ubuntu1404	ubuntu1604	ubuntu1610
#2	ubuntu14.04	ubuntu16.04	ubuntu16.10

1. Install Swift 4.0.3 to swiftenv: swiftenv install https://swift.org/builds/swift-4.0.3-release/#1/swift-4.0.3-RELEASE/swift-4.0.3-RELEASE-#2.tar.gz

That's it! Swift 4.0.3 is installed on your Ubuntu device and you can check with swift --version to make sure you're running Swift 4.0.3

Nice

i am trying install Swift 4.0.3 the newest version but not working when i want install Swift every time the terminal give me :

https://swift.org/builds/swift-4.0.3-release/ubuntu1610/swift-4.0.3-RELEASE/swift-4.0.3-RELEASE-ubuntu16.10.tar.gz

bash: https://swift.org/builds/swift-4.0.3-release/ubuntu1610/swift-4.0.3-RELEASE/swift-4.0.3-RELEASE-ubuntu16.10.tar.gz: No such file or directory

You have to include the swiftenv install command, like this: swiftenv install https://swift.org/builds/swift-4.0.3-release/ubuntu1610/swift-4.0.3-RELEASE/swift-4.0.3-RELEASE-ubuntu16.10.tar.gz

Thanks!

you can also just do swiftenv install 4.0.3 and it'll figure out the URL.

Thanks, it was helpful :)

You are G.O.A.T

Well, I put
swiftenv install https://swift.org/builds/swift-4.0-release/ubuntu1604/swift-4.0-RELEASE/swift-4.0-RELEASE-ubuntu16.04.tar.gz
and have
home/parallels/.swiftenv/libexec/../libexec/swiftenv-install: line 101: curl: command not found
Can it be caused by parallels?

Having a similar problem installing on a virtual machine under VMWare Fusion on a Mac Pro running OS X 10.11.6. What I see is:
Downloading https://swift.org/builds/swift-4.0.3-release/ubuntu1604/swift-4.0.3-RELEASE/swift-4.0.3-RELEASE-ubuntu16.04.tar.gz
/tmp/swiftenv-4.0.3-RELEASE-robertbuckley ~
/home/robertbuckley/.swiftenv/libexec/../libexec/swiftenv-install: line 94: curl: command not found

Everything went as described until that final step

Thanks a lot !

@drbuckleyjr Run sudo apt-get update && sudo apt-get install curl libcurl4

Thanks !!!

Full steps, Ubuntu 18.04, Swift 5.0.2:

sudo apt-get update
sudo apt-get -y install curl libcurl4 libcurl4-openssl-dev clang libicu-dev
mkdir ~/.swiftenv
git clone https://github.com/kylef/swiftenv ~/.swiftenv
echo 'export SWIFTENV_ROOT="$HOME/.swiftenv"' >> ~/.bashrc
echo 'export PATH="$SWIFTENV_ROOT/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(swiftenv init -)"' >> ~/.bashrc
source ~/.bashrc
swiftenv install https://swift.org/builds/swift-5.0.2-release/ubuntu1804/swift-5.0.2-RELEASE/swift-5.0.2-RELEASE-ubuntu18.04.tar.gz
swift --version
