Can I use color literals in SwiftUI

Easy Drag and Drop Color for Xcode Swift UI

I find it helpful when designing layouts where I need to find and adjust a color quickly to use this method.

I do this whenever I want to use the drag and drop style color literals in SwiftUI.

Later, I can go back and add the hard coded color to my color scheme simply by commenting out "//" the color literal line in my code which reveals the RGB for my selected color.

Hope that helps.

UPDATE: As of Xcode 13.2.1

Quite possibly it came out earlier but I didn’t catch it.

To get the autocomplete to work, type this line into your code.

#colorLiteral()

Then the code will automatically place the literal in the code for you to make the selection.

Note: From Xcode 11 Beta 5, Color has an initializer for this already and no need to implement it.

So you can use colorLiteral like this:

Color(#colorLiteral(red: 1, green: 0, blue: 0, alpha: 1))

Or any other CGColor, UIColor (or NSColor for macOS):

Color(.red)

You can use a Color defined in Asset Catalog by passing the string name inside the init.

So, if I have the "Background" color inside my Assets.xcassets:

I will use:

let backgroundColor = Color("Background")

Alternatively if the color is defined in another Bundle you can use:

Color(name: String, bundle: Bundle)

P.S. It's seem that Color Literals doesn't work with the Asset color's
