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.
