Unlocking the Full Potential of ColorPicker in SwiftUI

Have you ever wanted to enhance user interaction in your SwiftUI app? Specifically, do you want your ColorPicker to respond not only when users tap the color circle but also when they engage with a label? If you've been wondering how to achieve that in SwiftUI, you're in the right place!

In this guide, we'll walk through a straightforward solution that combines SwiftUI with UIKit to create an interactive ColorPicker with an active label. Let's dive into the problem and then explore the effective solution.

The Problem

By default, a ColorPicker component in SwiftUI allows users to pick a color, but it only opens the color selection modal when the color circle is tapped. What if you want the same functionality when users tap on a descriptive label? This is a common requirement for creating a more user-friendly experience in your application.

The Solution

Starting from iOS 15, you can achieve this functionality using SwiftUI and UIKit together. Here’s how to implement it step by step:

Step 1: Create a Custom ColorPickerPanel

To start, we need to create a new SwiftUI view that will serve as a bridge to UIKit’s UIColorPickerViewController. Below is the code to create this custom view:

Step 2: Integrate the ColorPickerPanel in Your Main View

Now that we have our custom ColorPickerPanel, let’s use it in our main view (ContentView). This example below illustrates how to present the color picker when either the color circle or the label is tapped:

Explanation of Key Components

ColorPickerPanel: This custom struct acts as a wrapper for the UIKit's UIColorPickerViewController and makes it usable within SwiftUI.

Coordinator: This class helps manage the interaction between the SwiftUI view and the UIKit color picker to ensure that the selected color updates seamlessly.

Main View: The ContentView utilizes the label (Label) and other SwiftUI components to create an interactive user interface, allowing color selection through both the label and the color swatch.

Conclusion

By combining SwiftUI with UIKit, your app can deliver a richer user experience with an interactive ColorPicker. Users can easily access color picking from both the color circle and the linked label, enhancing usability and engagement.

Now it's your turn! Go ahead and implement this solution in your own SwiftUI projects and watch how it improves the way users interact with color settings.
