Dev Swatches

• See all of the colors provided by SwiftUI and UIKit in a single place.
• Preview adaptive colors in both light and dark mode without leaving the applications or changing your system settings.
• Check the translucency in system colors using the checkerboard backdrop.
• Preview text colors with a custom string.
• Review which colors are supported on which devices, since tvOS and watchOS don't support the full set of colors provided by macOS or iOS.
