ColorSelector

A SwiftUI color picker component library for macOS, designed to replace the default ColorPicker component. In addition, I’ve created another component library, Colorful, which offers a different user experience with a distinct style.

Welcome to download DevTutor, a cheat sheet app designed to help developers quickly build excellent applications using SwiftUI.

Usage

import ColorSelector

struct ContentView: View {
    @State var color: Color? = .red
    @State var colorClear: Color? = .clear
    @State var nsColor: NSColor? = NSColor.red
    
    var body: some View {
        ColorSelector("Color", selection: $color)
        ColorSelector(selection: $colorClear)
        ColorSelector(nsColor: $nsColor, arrowEdge: .top)
        ColorSelector(selection: $color) {
            Text("Color Picker")
        }
        ColorSelector(selection: $color, footer: {
            Text("Hello World")
        })
        ColorSelector(selection: $color, footer: {
            Text("Hello World")
        }) {
            Text("Color Picker Footer")
        }
        ColorSelector(nsColor: $nsColor, footer: {
            Text("Hello World")
        })
    }
}

Using the swatchColors environment value, developers can customize the color list in the color selector, replacing the default color options.

struct ContentView: View {
    @State var color: Color? = .red
    
    var body: some View {
        ColorSelector(selection: $color)
            .environment(\.swatchColors, [
                NSColor(hue: 0.999, saturation: 0.857, brightness: 0.878, alpha: 1.0),
                NSColor(hue: 0.066, saturation: 1.000, brightness: 0.980, alpha: 1.0),
                NSColor(hue: 0.121, saturation: 0.976, brightness: 0.969, alpha: 1.0),
            ])
        ///     
        ColorSelector(selection: $colorClear, arrowEdge: .top)
    }
}

By setting the cornerSize (corner radius) and pointSize (point size) environment values, the corner radius and point size can be dynamically adjusted.

struct ContentView: View {
    @State var color: Color? = .red
    @State var cornerRadius: CGFloat = 6
    @State var pointSize: CGSize = .init(width: 12, height: 12)
    
    var body: some View {
        ColorSelector(selection: $color)
            .environment(\.cornerSize, cornerRadius)
            .environment(\.pointSize, pointSize)
    }
}

arrowEdge: The edge of the attachmentAnchor that defines the location of the popover’s arrow. The default is nil, which results in the s
