Contributing

This is a repository of skills for iOS developers, but that doesn’t mean it’s a dumping ground for half-baked, unchecked material.

If you want to contribute a link here, please ensure that:

• It was written by a human, not AI. The whole point of skills is to provide agents with things they do not already know; writing them with AI completely undermines that.
• The repository has not plagiarized other authors. We shouldn’t have to say this, but please be respectful of other people and their work – make your own stuff rather than copying other people’s.
• The repository uses a license that is compatible with working on the App Store, such as MIT, Apache 2, BSD (2- and 3-clause), ISC license, and Unlicense. GPLv2, GPLv3, and LGPL are not compatible.
• The text you’re adding to this README file is about the same length as others, to avoid taking over the page.
• You add a GitHub link to your profile with your name next to it, so people can verify they trust you.

You also agree to abide by the Code of Conduct.

Note: If you have many skills, please pick a handful of the most important to add so it doesn’t look like you’re just spamming the repository.

This repository was created by Paul Hudson, who writes free Swift tutorials over at Hacking with Swift. The repository itself is available under the MIT License, which permits commercial use, modification, distribution, and private use, but the links and summaries belong to others.

I don’t own the content in most of the linked repositories, and they each have their own licenses that you should read as appropriate. Being listed here is not an endorsement from me.
