Usage

Programmatically

Create TelegramColorPicker instance then add it as a subview.

let frame = CGRect(x: .zero, y: .zero, width: 400, height: 250)
let colorPicker = TelegramColorPicker(frame: frame)
view.addSubview(colorPicker)

Storyboard

Drag UIView object from the object library and set TelegramColorPicker as a custom class in identity inspector.
Create and connect @IBOutlet with TelegramColorPicker type.

SwiftUI

Create struct that conforms to UIViewRepresentable protocol:

struct TelegramColorPickerRepresentable: UIViewRepresentable {
    func makeUIView(context: Context) -> TelegramColorPicker {
        TelegramColorPicker()
    }
    func updateUIView(_ uiView: TelegramColorPicker, context: Context) { }
}

use it in your View:

var body: some View {
        TelegramColorPickerRepresentable()
        .frame(width: 400, height: 250, alignment: .center)
}

Get color update

Use getColorUpdate function with your custom closure and don't forget to use [weak self] to avoid strong reference cycle.

getColorUpdate { [weak self] (_, color) in
           guard let newColor = color.newValue, let hexadecimalColor = newColor.toHex() else { return }
           self?.textLabel.text = hexadecimalColor
}
