xcodes

The best command-line tool to install and switch between multiple versions of Xcode.

If you're looking for an app version of xcodes, try Xcodes.app.

Installation

Homebrew (Preferred)

brew install robotsandpencils/made/xcodes

These are Developer ID-signed and notarized release builds and don't require Xcode to already be installed in order to use.

Other methods:

Download a release

Download the latest release from the Releases page. These are Developer ID-signed release builds and don't require Xcode to already be installed in order to use.

Using Mint

mint install RobotsAndPencils/xcodes

Build from source

Building from source requires Xcode 12.0 or later, so it's not an option for setting up a computer from scratch.

git clone https://github.com/RobotsAndPencils/xcodes
cd xcodes
make install
# or, if /usr/local/ isn't in your PATH
PREFIX=/your/install/directory make install

While installing, you may get the following output:

swift build
error: terminated(72): xcrun --sdk macosx --find xctest output:

If that occurs, it means you need to select a version of Xcode. You can do this with xcode-select or by choosing a Command Line Tools option in Xcode's preferences Locations tab.

Usage

Install a specific version of Xcode using a command like one of these:

xcodes install 10.2.1
xcodes install 11 Beta 7
xcodes install 11.2 GM seed
xcodes install 9.0 --path ~/Archive/Xcode_9.xip
xcodes install --latest-prerelease
xcodes install --latest --directory "/Volumes/Bag Of Holding/"

You'll then be prompted to enter your Apple ID username and password. You can also provide these with the XCODES_USERNAME and XCODES_PASSWORD environment variables.

After successfully authenticating, xcodes will save your Apple ID password into the keychain and will remember your Apple ID for future use. If you need to use a different Apple ID than the one that's remembered, set the XCODES_USERNAME environment variable.

xcodes will download and install the version you asked for so that it's ready to use.

(1/6) Downloading Xcode 11.2.0: 100%
(2/6) Unarchiving Xcode (This can take a while)
(3/6) Moving Xcode to /Applications/Xcode-11.2.0.app
(4/6) Moving Xcode archive Xcode-11.2.0.xip to the Trash
(5/6) Checking security assessment and code signing
(6/6) Finishing installation
xcodes requires superuser privileges in order to finish installation.
macOS User Password:

Xcode 11.2.0 has been installed to /Applications/Xcode-11.2.0.app

If you have aria2 installed (it's available in Homebrew, brew install aria2), then xcodes will default to use it for downloads. It uses up to 16 connections to download Xcode 3-5x faster than URLSession.

Xcode will be installed to /Applications by default, but you can provide the path to a different directory with the --directory option or the XCODES_DIRECTORY environment variable. All of the xcodes commands support this option, like select and uninstall, so you can manage Xcode versions that aren't in /Applications. xcodes supports having all of your Xcode versions installed in one directory, wherever that may be.

Commands

download <version>: Download a specific version of Xcode
install <version>: Download and install a specific version of Xcode
installed: List the versions of Xcode that are installed
list: List all versions of Xcode that are available to install
select: Change the selected Xcode
uninstall: Uninstall a specific version of Xcode
update: Update the list of available versions of Xcode
version: Print the version number of xcodes itself
signout: Clears the stored username and password

Shell Completion Scripts

xcodes can generate completion scripts which allow you to press the tab key on your keyboard to autocomplete commands and arguments when typing an xcodes command. The steps to install a completion script depend on the shell that you use. More information about installation instructions for different shells and the underlying implementation is available in the swift-argument-parser repo.

Zsh, with oh-my-zsh:

Run the following commands:

mkdir ~/.oh-my-zsh/completions
xcodes --generate-completion-script > ~/.oh-my-zsh/completions/_xcodes

Development

You'll need Xcode 12 in order to build and run xcodes.

Using Xcode

Even though xcodes is a command-line app, lll of the normal functionality works in Xcode, like building, running, and running tests. You can even type text into Xcode's console when it prompts you for input like your Apple ID or 2FA code.

When running xcodes from Xcode, if you want to run a particular command or pass some arguments, you can hold the option key to present a sheet with more options. This means you'd use Option + Command + R or hold Option while clicking the Run button. Here you can add, remove, and toggle arguments that will be passed to xcodes when it's launched.

Using Swift command line tools

You can also use the Swift command line tools once you have Xcode installed:

Build: swift build
Run: swift run, or commands like swift run xcodes list
Run tests: swift test

There's a Makefile to help build xcodes for distribution. We already do this for you in order to provide Developer ID-signed and notarized release builds via Homebrew (see Installation).

Releasing a new version of xcodes

# Bump the version number in Version.swift, commit the change, and tag it
vim Sources/XcodesKit/Version.swift
git add Sources/XcodesKit/Version.swift
git commit -m "Bump version to $VERSION"
git tag -asm "$VERSION" "$VERSION"

# Clean first
make clean

# Make a release build of xcodes, sign it, and zip it
make zip
# Create a Homebrew bottle
make bottle VERSION="$VERSION"

# Notarize the release build
# This can take a while
make notarize \
    USERNAME="user@example.com" \
    PASSWORD="@keychain:ALTool Notarization" \
    ASC_PROVIDER="YourAppStoreConnectTeamName"

# Push the new version bump commit and tag
git push --follow-tags

# Edit the draft release created by Release Drafter to point at the new tag
# Set the release title to the new version
# Add the xcodes.zip and xcodes-$VERSION.mojave.tar.gz files to the release
# Publish the release

# Update the Homebrew Bottle: https://github.com/RobotsAndPencils/homebrew-made/blob/master/Formula/xcodes.rb

Notable design decisions are recorded in DECISIONS.md. The Apple authentication flow is described in Apple.paw, which will allow you to play with the API endpoints that are involved using the Paw app.

xcode-install and fastlane/spaceship both deserve credit for figuring out the hard parts of what makes this possible.
