This guide shows you how to install and use the tool with the most common configuration. For advanced options and complete reference information, see the official documentation. Some install guides also include optional next steps to help you explore related workflows or integrations.

[Swift](https://swift.org/) is an open-source programming language initially developed by Apple for use with Apple’s iOS, macOS, watchOS, and tvOS operating systems. It has since gained popularity as a general-purpose language suitable for a wide range of Linux and Windows applications. Swift is known for its safety, speed, and expressiveness, making it ideal for both beginners and experienced programmers.

Swift is available for macOS, Windows, and Linux, including Arm Linux distributions. In this guide, you’ll learn how to install Swift on Ubuntu for Arm.

## Before you begin

Confirm you are using an Arm machine by running:

```bash
uname -m
```

The output should be:

```bash
__output__ aarch64
```

If you see a different result, you are not using an Arm computer running 64-bit Linux.

### Required software packages

Before you install Swift on Ubuntu 24.04, install the following packages:

```bash
sudo apt update
sudo apt-get -y 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 and install Swift

Download Swift for Arm Linux:

> **Note**  
> The following commands use Swift version 6.3.3 on Ubuntu 24.04. The same commands work with other versions. Replace the file used in these steps with the file for your version of choice. To find all available versions, see [Download Swift](https://www.swift.org/download/).

```bash
wget https://download.swift.org/swift-6.3.3-release/ubuntu2404-aarch64/swift-6.3.3-RELEASE/swift-6.3.3-RELEASE-ubuntu24.04-aarch64.tar.gz
```

Extract the archive:

```bash
sudo tar -xf swift-6.3.3-RELEASE-ubuntu24.04-aarch64.tar.gz -C /usr/local
```

Add the `bin/` directory to your search path:

```bash
echo 'export PATH="$PATH:/usr/local/swift-6.3.3-RELEASE-ubuntu24.04-aarch64/usr/bin"' >> ~/.bashrc
source ~/.bashrc
```

## Confirm Swift is working

To confirm Swift is working, print the version:

```bash
swift --version
```

The output is similar to:

```bash
__output__ Swift version 6.3.3 (swift-6.3.3-RELEASE)
__output__ Target: aarch64-unknown-linux-gnu
```

You can also create and run a simple example program.

Use a text editor to create a new file named `hello.swift` and add the following code:

```swift
print("Hello from Swift on Arm Linux!")
```

Compile and run the program:

```bash
swift hello.swift
```

The output will be similar to:

```bash
__output__ Hello from Swift on Arm Linux!
```

You can also compile and run the program using:

```bash
swiftc hello.swift -o hello
./hello
```

The output will be the same:

```bash
__output__ Hello from Swift on Arm Linux!
```

You are now ready to use the Swift programming language on your Arm Linux computer.
