EditableColor

A mutable color representation that conforms to ObservableObject with automatic, dead-simple bridging to SwiftUI, UIKit, and AppKit.

This package contains all the model code necessary to roll your own color picker.

Minimum SDK for EditableColor: None

Minimum SDK for UIKit & AppKit Bridging: iOS 10 & macOS 10.12 Sierra

Minimum SDK for SwiftUI Bridging: iOS 13 & macOS 10.15 Catalina

Installation

In Xcode: File > Swift Packages > Add Package Dependency... (https://github.com/DonSwet/EditableColor.git)

Usage

Create an instance of EditableColor

import EditableColor

// Start with component values.
let color = EditableColor(red: 1, green: 1, blue: 1, alpha: 1, colorspace: .sRGB)

// OR start with no values. Default: (red: 1, green: 1, blue: 1, alpha: 1, colorspace: .sRGB)
let color = EditableColor()

// To change the default initializer arguments, you can edit this static proxy value.
EditableColor.defaultValues.red = 0

SwiftUI - Using EditableColor in place of Color

If you need to use an EditableColor in the form of SwiftUI's native Color type, you may do so. Changes made to the EditableColor will not reflect in real-time unless it's stored using an @ObservedObject or EnvironmentObject property wrapper in the relevant view or one of its parents.

struct ContentView: some View {
	@ObservedObject var color: EditableColor

	var body: some View {
		Text("Hello World!")
			.foregroundColor(Color(color))
	}
}

UIKit & AppKit

This is a one-time-use bridge. A UIColor or NSColor instance generated from an EditableColor will not automatically display changes made to its original EditableColor. You'll have to replace it manually upon any changes.

let swiftuiColor = Color(color)
let uiColor = UIColor(color)
let nsColor = NSColor(color)
