UIColor to SwiftUI.Color extension

UIColor+Color.swift

extension UIColor {
	func color(with colorScheme: ColorScheme) -> Color {
        var red: CGFloat = 0
        var blue: CGFloat = 0
        var green: CGFloat = 0
        var alpha: CGFloat = 0

        let trait: UITraitCollection = {
            switch colorScheme {
            case .light:
                return UITraitCollection(userInterfaceStyle: .light)
            case .dark:
                return UITraitCollection(userInterfaceStyle: .dark)
            @unknown default:
                return UITraitCollection(userInterfaceStyle: .light)
            }
        }()

        resolvedColor(with: trait).getRed(&red, green: &green, blue: &blue, alpha: &alpha)

        return Color(red: Double(red), green: Double(green), blue: Double(blue)).opacity(Double(alpha))
    }
}

// To use add this to your View struct
@Environment(\.colorScheme) var colorScheme: ColorScheme
// then this is usable and responds to changing the color scheme from light to dark
UIColor.tertiarySystemBackground.color(with: colorScheme)

Came up with this with the help of a coworker.
