GradientAttributes

A Swift library that simplifies the use of a CAGradientLayer.

Why?

Creating attributes for a CAGradientLayer can be tedious:

• Colors and Locations array must be typed as [AnyObject]
• Colors and Locations are provided by separate arrays instead of together as a pair of related values.
• Colors must return CGColor as values
• Changing the direction of a gradient to common directions is non-obvious and unclear when reading code.
• A location value must be provided along with each color, which could be tedious to maintain.

GradientAttributes improves this experience by providing a nicer syntax for defining color stops, as well as providing additional logic to interpolate location values so you only need to provide what you care about.

How?

For now, see the tests and code for usage details.

TODO

• Document usage in README
• Expand options for setting direction beyond simply Horizontal/Vertical. Probably will be able to specify common start and end locations.
• Verify that this can be installed as a framework.
• Add .playground that demonstrates usage. Currently having problems importing module into the playground.
• See if there's a better syntax for defining gradient stops in an array.
