Swift - create array of custom colors - ios

Question

Is there a way to create an array of custom colors? I know I can create custom colors in class UIColors but in my case I need an array of my custom colors.
I would like to achieve something like this:
let listColors: [UIColor] = [
let color1 = UIColor(displayP3Red: 1, green: 1, blue: 1, alpha: 1),
let color2 = UIColor(displayP3Red: 2, green: 2, blue: 2, alpha: 1),
let color3 = UIColor(displayP3Red: 3, green: 3, blue: 3, alpha: 1),
]

You don't need a subclass to create an array do
let listColors = [
UIColor(displayP3Red: 1, green: 1, blue: 1, alpha: 1),
UIColor(displayP3Red: 2, green: 2, blue: 2, alpha: 1),
UIColor(displayP3Red: 3, green: 3, blue: 3, alpha: 1)
]
access
listColors[index]
or
class Colors {
static let color1 = UIColor(displayP3Red: 1, green: 1, blue: 1, alpha: 1)
static let color2 = UIColor(displayP3Red: 2, green: 2, blue: 2, alpha: 1)
static let color3 = UIColor(displayP3Red: 3, green: 3, blue: 3, alpha: 1)
}
access
Colors.color1
or as global
let color1 = UIColor(displayP3Red: 1, green: 1, blue: 1, alpha: 1)
let color2 = UIColor(displayP3Red: 2, green: 2, blue: 2, alpha: 1)
let color3 = UIColor(displayP3Red: 3, green: 3, blue: 3, alpha: 1)
access
color1
When you create a color divide by 255
UIColor(displayP3Red: 2/255.0, green: 2/255.0, blue: 2/255.0, alpha: 1)

Or if you want to be able to reference them by name or by array index:
let color1 = UIColor(red: 1.0, green: 1.0, blue: 1.0, alpha: 1.0), //White
let color2 = UIColor(red: 0.5, green: 0.5, blue: 0.5, alpha: 1.0), //Gray
let color3 = UIColor(red: 1.0, green: 0.0, blue: 0.0, alpha: 1.0), //Red
let listColors: [UIColor] = [color1, color2, color3]

If you are supporting dark and light modes in your App, it is best to define your custom colors as assets in your App and then access them something like this
extension String {
static let blueColorName = "Blue"
static let brownColorName = "Brown"
static let crustaColorName = "Crusta"
static let darkRedColorName = "DarkRed"
static let defaultColorName = "Default"
static let flamingoColorName = "Tango"
static let khakiColorName = "Khaki"
static let greenColorName = "Green"
static let limeColorName = "Lime"
static let lustColorName = "Lust"
static let oliveColorName = "Olive"
static let orangeColorName = "Orange"
static let pinkColorName = "Pink"
static let purpleColorName = "Purple"
static let roseColorName = "Rose"
static let redColorName = "Red"
static let skyColorName = "Sky"
static let steelColorName = "Steel"
static let sunColorName = "Sun"
static let tealColorName = "Teal"
static let yellowColorName = "Yellow"
// Tile Background Colors
static let tileGrayColorName = "TileGray"
static let tileGreenColorName = "TileGreen"
static let tileRedColorName = "TileRed"
static let tileYellowColorName = "TileYellow"
}
extension UIColor {
// MARK: - Custom Color List For Color Picker
static let customColorsList: [(colorName: String, uiColor: UIColor)] = [
("Orange", UIColor(named: .orangeColorName)!),
("Tango", UIColor(named: .flamingoColorName)!),
("Crusta", UIColor(named: .crustaColorName)!),
("Yellow", UIColor(named: .yellowColorName)!),
("Sun", UIColor(named: .sunColorName)!),
("Khaki", UIColor(named: .khakiColorName)!),
("Lime", UIColor(named: .limeColorName)!),
("Green", UIColor(named: .greenColorName)!),
("Olive", UIColor(named: .oliveColorName)!),
("Teal", UIColor(named: .tealColorName)!),
("Sky", UIColor(named: .skyColorName)!),
("Blue", UIColor(named: .blueColorName)!),
("Steel", UIColor(named: .steelColorName)!),
("Pink", UIColor(named: .pinkColorName)!),
("Rose", UIColor(named: .roseColorName)!),
("Purple", UIColor(named: .purpleColorName)!),
("Lust", UIColor(named: .lustColorName)!),
("Dark Red", UIColor(named: .darkRedColorName)!),
("Brown", UIColor(named: .brownColorName)!),
("Default", UIColor(named: .defaultColorName)!)
]
