Liftoff is a CLI for creating and configuring iOS Xcode projects.
👋 We need your help! We're looking for contributors and people willing to take over Liftoff maintenance. If you're interested, we'd love to hear from you! 👍
brew tap liftoffcli/formulae
brew install liftoff
Liftoff was previously distributed via RubyGems. This method of installation has been deprecated, and all new releases will be done through Homebrew. If you are migrating from RubyGems, you should uninstall the gem version to avoid confusion in the future.
Run this command in a directory
liftoff
View the documentation:
man liftoff
man liftoffrc
When Liftoff finds an existing project in the current directory, it will perform the following configurations:
- Set the indentation level (In spaces, 4 by default).
- Treat warnings as errors for release schemes.
- Enable warnings at the project level, check
liftoffrc(5)
for a list of the warnings. - Turn on Static Analysis for the project.
- Add a build phase shell script that turns "TODO:" and "FIXME:" into warnings.
- Add a build phase shell script that sets the version to the latest Git tag, and the build number to the number of commits on master.
- Perform arbitrary configuration as defined in the user's
liftoffrc
. Seeliftoffrc(5)
for more information. - Add default .gitignore and .gitattributes files.
- Initialize a new
git
repo and create an initial commit (if needed).
When you run Liftoff in a directory without a project file, it will create a new directory structure for a project, and generate a well-configured Xcode project in that subdirectory:
$ cd ~/dev/
$ liftoff
Project name? MyCoolApp
Company name? thoughtbot
Author name? Gordon Fontenot
Prefix? MCA
Creating MyCoolApp
Creating MyCoolApp/Categories
Creating MyCoolApp/Classes

Liftoff will generate a brand new project for you based on the provided values. Generating projects via Liftoff has these advantages:
- Minimized time reorganizing the repository
- Sets up
git
repository automatically - Defined group structure
- Matching directory structure on disk (linked to the proper group)
- Easily customizable
- Configurations can be shared easily
You can use a liftoffrc
file to speed up your workflow by defining your
preferred configuration for Liftoff.
Liftoff will look for config files in the local directory and then the home
directory. If it can't find a key in ./.liftoffrc
or ~/.liftoffrc
, it will
use the default values. Check liftoffrc(5)
for more information:
man liftoffrc
You can see the current liftoffrc on master, but be aware that the keys might not match up completely with the current released version.
One of the most powerful things that Liftoff can do for you is let you quickly
and easily customize your project's group and directory structure. By defining
a YAML dictionary inside your local or user .liftoffrc
, you can completely
dictate the structure that will be created. This includes group structure,
order, placement of template files, etc. And remember that these groups will
be mimicked on disk as well.
You can also create your own templates, or override the defaults by adding
them to ~/.liftoff/templates
or ./.liftoff/templates
. Liftoff will use the
same fallback order when looking for templates as it does for the
.liftoffrc
.
These files (and filenames) will be parsed with ERB
, using the values
provided at run time (or the default values from a liftoffrc
).
