IGListKit is built and maintained with ❤️ by Instagram engineering.
We use the open source version
master branch in the Instagram app.
The preferred installation method is with CocoaPods. Add the following to your
pod 'IGListKit', '~> 4.0.0'
For Carthage, add the following to your
github "Instagram/IGListKit" ~> 4.0.0
To integrate using Xcode: File -> Swift Packages -> Add Package Dependency Enter package URL: https://github.com/Instagram/IGListKit, and select the latest release.
For advanced usage, see our Installation Guide.
$ git clone https://github.com/Instagram/IGListKit.git $ cd IGListKit/ $ ./scripts/setup.sh
To regenerate docs, run
./scripts/build_docs.sh from the root directory in the repo.
For the long-term goals and "vision" of
IGListKit, please read our Vision doc.
Please see the CONTRIBUTING file for how to help. At Instagram, we sync the open source version of
IGListKit daily, so we're always testing the latest changes. But that requires all changes be thoroughly tested and follow our style guide.
We have a set of starter tasks that are great for beginners to jump in on and start contributing.
IGListKit is MIT-licensed.
The files in the
/Examples/ directory are licensed under a separate license as specified in each file. Documentation is licensed CC-BY-4.0.
