How to Install Swift on Ubuntu 24.04

Prepare Ubuntu

To install Swift Ubuntu 24.04 safely, you need to check your exact system version first to avoid compatibility errors. Open your terminal and run the lsb_release -a command to confirm you are running the correct noble release before you download any files.

Download the ⬇️ appropriate release package matching the target environment architecture.

Run the command to verify the Ubuntu release and codename of your system.

lsb_release -a

Systems running Ubuntu 24.04 return release version 24.04 alongside the noble codename.

Fetch the required dependency packages using the system package manager.

sudo apt-get install binutils git gnupg2 libc6-dev libcurl4-openssl-dev libedit2 libgcc-13-dev libncurses-dev libpython3-dev libsqlite3-0 libstdc++-13-dev libxml2-dev libz3-dev pkg-config tzdata unzip zlib1g-dev

Download Swift

To install Swift Ubuntu 24.04 successfully, you need to download the official release binary using the wget file retrieval tool. Run the wget command in your terminal to fetch the latest package directly from the Swift download site and match your system architecture.

The command below downloads Swift 6.0.3 binary; remember to replace the version number with the latest.

wget https://download.swift.org/swift-6.0.3-release/ubuntu2404/swift-6.0.3-RELEASE/swift-6.0.3-RELEASE-ubuntu24.04.tar.gz

Grabbing the GPG key (a cryptographic signature used to verify package authenticity) secures the installation process. Run this command:

Download the Swift signature file for the installer, and then use the command below to verify it, ensuring the downloaded file is genuine.

wget https://download.swift.org/swift-6.0.3-release/ubuntu2404/swift-6.0.3-RELEASE/swift-6.0.3-RELEASE-ubuntu24.04.tar.gz.sig
gpg --verify swift-6.0.3-RELEASE-ubuntu24.04.tar.gz.sig

Extract the downloaded installer archive and move the resulting folder into the /opt directory.

tar xzf swift-6.0.3-RELEASE-ubuntu24.04.tar.gz
sudo mv swift-6.0.3-RELEASE-ubuntu24.04/* /opt/swift

Configure Swift

To make the compiler work from any terminal window when you install Swift Ubuntu 24.04, you must add the installation folder to your system PATH variable. Run the echo command to update your profile and load the new settings immediately without restarting your computer.

echo "export PATH=$PATH:/opt/swift/usr/bin" >> $HOME/.profile
source $HOME/.profile

Executing the command below confirms the compiler binary responds correctly.

swift --version

The terminal outputs the specific compiler version currently active in the environment.

Launching the interactive read-eval-print loop starts the Swift REPL environment.

That completes the setup process.
