[swift-evolution] VisualFoundation Framework

[Erica Sadun]

These are inherently cross-platform concepts that can be represented both as literals (like the current color, file, and image) or as Swift-specific types, allowing the realization details to be pushed to platforms (macOS, iOS, common linux libraries).

Some ideas about literals here: https://gist.github.com/erica/c92f6ab115af89d5c4b9161487df6a3c <https://gist.github.com/erica/c92f6ab115af89d5c4b9161487df6a3c>
Some ideas about types and functionality for core graphics here: https://github.com/erica/SwiftGeometry/tree/master/Sources <https://github.com/erica/SwiftGeometry/tree/master/Sources>

If this idea has traction, it probably needs to be a separate development list or working group.

I am suggesting creating a very small open source swift-corelib that sits on top of foundation, and adds basic visual concepts like Color, Image, AttributedText, and (hat tip to T.J.) BezierPaths.  Things where the concepts themselves are completely cross-platform, and they really should be in foundation, except that they are visual concepts, and thus got packaged with the whole platform framework for historical reasons.

These are both Apple frameworks, which you can discuss on the Apple mailing lists. To find the appropriate one, you can consult https://lists.apple.com/mailman/listinfo <https://lists.apple.com/mailman/listinfo> - I would suggest the cocoa-dev mailing list.
