Swift is covered by the Swift License at swift.org/LICENSE.txt.

Using Downloads

Apple Platforms

Xcode includes a release of Swift that is supported by Apple. You can try out a version that is still in development by downloading one of the packages above.

To submit to the App Store you must build your app using the version of Swift that comes included within Xcode.

Requirements for Tools

Swift 5.1

Swift 5.0

Swift 4.2

Swift 4.1

Swift 4.0

Swift 3.1

Swift 3.0

Swift 2.2.x

Supported Target Platforms


Installation

  1. Download the latest package release.

  2. Run the package installer, which will install an Xcode toolchain into /Library/Developer/Toolchains/.

    An Xcode toolchain (.xctoolchain) includes a copy of the compiler, lldb, and other related tools needed to provide a cohesive development experience for working in a specific version of Swift.

  3. Open Xcode’s Preferences, navigate to Components > Toolchains, and select the installed Swift toolchain.

  4. Xcode uses the selected toolchain for building Swift code, debugging, and even code completion and syntax coloring. You’ll see a new toolchain indicator in Xcode’s toolbar when Xcode is using a Swift toolchain. Select the Xcode toolchain to go back to Xcode’s built-in tools.

  5. Selecting a Swift toolchain affects the Xcode IDE only. To use the Swift toolchain with command-line tools, use xcrun --toolchain swift and xcodebuild -toolchain swift, or add the Swift toolchain to your path as follows:

$ export PATH=/Library/Developer/Toolchains/swift-latest.xctoolchain/usr/bin:"${PATH}"

Code Signing on macOS

The macOS .pkg files are digitally signed by the developer ID of the Swift open source project to allow verification that they have not been tampered with. All binaries in the package are signed as well.

The Swift toolchain installer on macOS should display a lock icon on the right side of the title bar. Clicking the lock brings up detailed information about the signature. The signature should be produced by Developer ID Installer: Swift Open Source (V9AUD2URP3).

If the lock is not displayed or the signature is not produced by the Swift open source developer ID, do not proceed with the installation. Instead, quit the installer and please email swift-infrastructure@forums.swift.org with as much detail as possible, so that we can investigate the problem.

Linux

Packages for Linux are tar archives including a copy of the Swift compiler, lldb, and related tools. You can install them anywhere as long as the extracted tools are in your PATH.

Note that nothing prevents Swift from being ported to other Linux distributions beyond the ones mentioned below. These are only the distributions where these binaries have been built and tested.

  1. Download the latest binary release above.

    The swift-<VERSION>-<PLATFORM>.tar.gz file is the toolchain itself. The .sig file is the digital signature.

  2. If you are downloading Swift packages for the first time, import the PGP keys into your keyring:

    $ gpg --keyserver hkp://keyserver.ubuntu.com \
          --recv-keys \
          '7463 A81A 4B2E EA1B 551F  FBCF D441 C977 412B 37AD' \
          '1BE1 E29A 084C B305 F397  D62A 9F59 7F4D 21A5 6D5F' \
          'A3BA FD35 56A5 9079 C068  94BD 63BC 1CFE 91D3 06C6' \
          '5E4D F843 FB06 5D7F 7E24  FBA2 EF54 30F0 71E1 B235' \
          '8513 444E 2DA3 6B7C 1659  AF4D 7638 F1FB 2B2B 08C4' \
          'A62A E125 BBBF BB96 A6E0  42EC 925C C1CC ED3D 1561' \
          '8A74 9566 2C3C D4AE 18D9  5637 FAF6 989E 1BC1 6FEA' \
          'E813 C892 820A 6FA1 3755  B268 F167 DF1A CF9C E069'
    

    or:

    $ wget -q -O - https://swift.org/keys/all-keys.asc | \
      gpg --import -
    

    Skip this step if you have imported the keys in the past.

  3. Verify the PGP signature.

    The .tar.gz archives for Linux are signed using GnuPG with one of the keys of the Swift open source project. Everyone is strongly encouraged to verify the signatures before using the software.

    First, refresh the keys to download new key revocation certificates, if any are available:

    $ gpg --keyserver hkp://keyserver.ubuntu.com --refresh-keys Swift
    

    Then, use the signature file to verify that the archive is intact:

    $ gpg --verify swift-<VERSION>-<PLATFORM>.tar.gz.sig
    ...
    gpg: Good signature from "Swift Automatic Signing Key #4 <swift-infrastructure@forums.swift.org>"
    

    If gpg fails to verify because you don’t have the public key (gpg: Can't check signature: No public key), please follow the instructions in Active Signing Keys below to import the keys into your keyring.

    You might see a warning:

    gpg: WARNING: This key is not certified with a trusted signature!
    gpg:          There is no indication that the signature belongs to the owner.
    

    This warning means that there is no path in the Web of Trust between this key and you. The warning is harmless as long as you have followed the steps above to retrieve the key from a trusted source.

    If gpg fails to verify and reports “BAD signature”, do not use the downloaded toolchain. Instead, please email swift-infrastructure@forums.swift.org with as much detail as possible, so that we can investigate the problem.

  4. Extract the archive with the following command:

    $ tar xzf swift-<VERSION>-<PLATFORM>.tar.gz
    

    This creates a usr/ directory in the location of the archive.

  5. Add the Swift toolchain to your path as follows:

    $ export PATH=/path/to/usr/bin:"${PATH}"
    

    You can now execute the swift command to run the REPL or build Swift projects.

Active Signing Keys

The Swift project uses one set of keys for snapshot builds, and separate keys for every official release. We are using 4096-bit RSA keys.

The following keys are being used to sign toolchain packages:

Expired Signing Keys

Windows

Dependencies

Swift has the following general dependencies:

Windows has the following additional platform specific dependencies:

Installation Instructions

Install using the Windows Package Manager

The Windows Package Manager can be found in the App Store or be installed directly.

The platform dependencies cannot be installed through the Windows Package Manager as the install rules do not install the components necessary.

winget install Git.Git
winget install Python.Python.3 --version 3.7.8

curl -sOL https://aka.ms/vs/16/release/vs_community.exe
start /w vs_community.exe --passive --wait --norestart --nocache ^
  --installPath "%ProgramFiles(x86)%\Microsoft Visual Studio\2019\Community" ^
  --add Microsoft.VisualStudio.Component.Windows10SDK.19041 ^
  --add Microsoft.VisualStudio.Component.VC.Tools.x86.x64
del /q vs_community.exe

winget install Swift.Toolchain

Traditional Installation

NOTE: The traditional installation process is required for Swift older than 5.4.2.

Swift has been tested with Visual Studio 2019. You will need to install Visual Studio with the following components. The installer for Swift is available in the Download section. The toolchain on Windows is installed to %SystemDrive%\Library\Developer\Toolchains.

The following Visual Studio components are required:

Component Visual Studio ID
MSVC v142 - VS 2019 C++ x64/x86 build tools (Latest) Microsoft.VisualStudio.Component.VC.Tools.x86.x64
Windows 10 SDK (10.0.17763.0)2 Microsoft.VisualStudio.Component.Windows10SDK.17763

The following additional Visual Studio components are recommended:

Component Visual Studio ID
Git for Windows Microsoft.VisualStudio.Component.Git
Python 3 64-bit (3.7.8) Component.CPython.x64

The following additional Visual Studio components are suggested:

Component Visual Studio ID
C++ CMake tools for Windows Microsoft.VisualStudio.Component.VC.CMake.Project

Support Files

NOTE: This is only required for versions older than 5.4.2

You must use the x64 Native Tools for VS2019 Command Prompt to run the following steps. The x64 Native Tools for VS2019 Command Prompt runs the DevEnv script from Visual Studio that sets up the necessary environment variables to find the system headers.

In order to make the Windows SDK accessible to Swift, it is necessary to deploy a few files into the Windows SDK. The following will modify your Visual Studio Installation, and as such will require to be run from an (elevated) “Administrator” x86 Native Tools for VS2019 Command Prompt.

copy /Y %SDKROOT%\usr\share\ucrt.modulemap "%UniversalCRTSdkDir%\Include\%UCRTVersion%\ucrt\module.modulemap"
copy /Y %SDKROOT%\usr\share\visualc.modulemap "%VCToolsInstallDir%\include\module.modulemap"
copy /Y %SDKROOT%\usr\share\visualc.apinotes "%VCToolsInstallDir%\include\visualc.apinotes"
copy /Y %SDKROOT%\usr\share\winsdk.modulemap "%UniversalCRTSdkDir%\Include\%UCRTVersion%\um\module.modulemap"

Because it is installing the files into the Visual Studio image, the files will need to be copied each time Visual Studio is updated.

Repairing after Visual Studio Updates

If Visual Studio is updated, you may have to repair the installation. See Microsoft’s instructions for repairing installed programs.

Code Signing on Windows

  1. Install GPG from GnuPG.org

  2. If you are downloading Swift packages for the first time, import the PGP keys into your keyring:

    $ gpg.exe --keyserver hkp://keyserver.ubuntu.com `
          --receive-keys `
          'A62A E125 BBBF BB96 A6E0  42EC 925C C1CC ED3D 1561' `
          '8A74 9566 2C3C D4AE 18D9  5637 FAF6 989E 1BC1 6FEA'
    

    or:

    $ wget https://swift.org/keys/all-keys.asc -UseBasicParsing | `
    Select-Object -Expand Content | gpg.exe --import -
    

    Skip this step if you have imported the keys in the past.

  3. Verify the PGP signature.

    The .exe installer for Windows are signed using GnuPG with one of the keys of the Swift open source project. Everyone is strongly encouraged to verify the signatures before using the software.

    First, refresh the keys to download new key revocation certificates, if any are available:

    $ gpg.exe --keyserver hkp://keyserver.ubuntu.com --refresh-keys Swift
    

    Then, use the signature file to verify that the archive is intact:

    $ gpg.exe --verify swift-<VERSION>-<PLATFORM>.exe.sig
    ...
    gpg: Good signature from "Swift Automatic Signing Key #3 <swift-infrastructure@swift.org>"
    

    If gpg fails to verify because you don’t have the public key (gpg: Can't check signature: No public key), please follow the instructions in Active Signing Keys below to import the keys into your keyring.

    You might see a warning:

    gpg: WARNING: This key is not certified with a trusted signature!
    gpg:          There is no indication that the signature belongs to the owner.
    

    This warning means that there is no path in the Web of Trust between this key and you. The warning is harmless as long as you have followed the steps above to retrieve the key from a trusted source.

    If gpg fails to verify and reports “BAD signature”, do not use the downloaded toolchain. Instead, please email swift-infrastructure@forums.swift.org with as much detail as possible, so that we can investigate the problem.

Active Signing Keys

The Swift project uses one set of keys for snapshot builds, and separate keys for every official release. We are using 4096-bit RSA keys.

The following keys are being used to sign toolchain packages:
