Usage

import SwiftUI
import Colors

struct ContentView: View {
    var body: some View {
        VStack {
            Text("Hello, World!")
                .foregroundColor(Color.disabledControlTextColor)
        }
        .padding()
    }
}

Extract color from UIColor/NSColor

Use this to add new/missing colors to the BaseColor and Color extension.

Extract from UIKit:

UIColor.systemPink.createInitializerFor(color: "systemPink")

Extract from AppKit:

NSColor.systemPink.createInitializerFor(color: "systemPink")

Output:

/// A color that represents the system-provided systemPink color.
public static let systemPink = Color.dynamicColor(
    light: .init(red: 1.00, green: 0.18, blue: 0.33, alpha: 1.00),
    dark: .init(red: 1.00, green: 0.18, blue: 0.33, alpha: 1.00)
)

How to add a new color

1. Add the color to the BaseColor struct.

   /// A color that represents the system-provided systemPink color.
   public static let systemPink = Color.dynamicColor(
       light: .init(red: 1.00, green: 0.18, blue: 0.33, alpha: 1.00),
       dark: .init(red: 1.00, green: 0.18, blue: 0.33, alpha: 1.00)
   )

2. Add the color to the Color extension.
   • Use the native Color,NSColor,UIColor.colorName where possible.
   • Add #if os(iOS) / #if os(macOS) where needed.
   • Example (works on almost all versions):

    /// A color that represents the system-provided pink color.
    public static var systemPink: Color {
    #if os(iOS) || os(tvOS)
        Color(UIColor.systemPink)
    #elseif os(macOS)
        Color(NSColor.systemPink)
    #else
        BaseColor.systemPink
    #endif
    }

   • Example 2 (works from a specific iOS/macOS version):

   /// A color that represents the system-provided cyan color.
   public static var systemCyan: Color {
   #if os(iOS) || os(tvOS)
       if #available(iOS 15.0, *) {
           Color(UIColor.systemCyan)
       } else {
           BaseColor.systemCyan
       }
   #elseif os(macOS)
       if #available(macOS 12.0, *) {
           Color(NSColor.systemCyan)
       } else {
           BaseColor.systemCyan
       }
   #else
           BaseColor.systemCyan
   #endif
   }
