Glyph

Make life with TextKit better

Glyph adds features and abstractions for working with TextKit. Some are for performance, some for convenience. You don't even need to know whether your system using 1 or 2. Glyph will not downgrade TextKit 2 views. But, it can be awful nice to swap between 1 and 2 quickly when debugging.

Installation

dependencies: [
    .package(url: "https://github.com/ChimeHQ/Glyph", branch: "main")

Contributing and Collaboration

I would love to hear from you! Issues or pull requests work great. Both a Matrix space and Discord are available for live help, but I have a strong bias towards answering in the form of documentation. You can also find me here.

I prefer collaboration, and would love to find ways to work together if you have a similar project.

I prefer indentation with tabs for improved accessibility. But, I'd rather you use the system you want and make a PR than hesitate because of whitespace.

By participating in this project you agree to abide by the Contributor Code of Conduct.
