Usage

Basic CircularSlider Example

Add import AdaptiveSlider to use CircularSlider in your project. Then, initialize it with the following parameters:

• value: A Binding representing the current value of the slider.
• in: The range within which the slider operates. Default is 0...1.
• step: The incremental step for the slider’s value. Default is 0.01.
• label: (optional) A custom label for the slider. Default is EmptyView().

import AdaptiveSlider

struct ContentView: View {
    @State private var sliderValue: Double = 50

    var body: some View {
        CircularSlider(value: $sliderValue, in: 0...100) {
            Text(String(format: "%.0f", sliderValue))
        }
    }
}

Customization Examples

Below are examples of how you can customize CircularSlider using its powerful modifiers:

Customizing Radius, Colors, and Line Width

Adjust the appearance of CircularSlider to suit your app’s design:

CircularSlider(value: $sliderValue, in: 0...100)
    .radius(120) // Sets the radius of the circular slider.
    .tint(.yellow) // Customizes the color of the progress track.
    .trackStyle(lineWidth: 10, color: .gray) // Configures the track’s width and color.
    .thumbStyle(radius: 8, color: .red) // Sets the thumb's radius and color.

Combining Ticks with Steps

Add ticks to visualize key values along with step increments. This enhances user interaction by providing clear visual markers.

CircularSlider(value: $sliderValue, in: 0...100, step: 10) {
    Text(String(format: "%.0f", sliderValue))
        .font(.title3)
        .fontWeight(.semibold)
}
.radius(60)
.trackStyle(lineWidth: 8)
.showTicks(count: 10) // Adds ticks to the slider for better visualization.

Gradient Progress Line

Create visually engaging sliders with gradient progress lines:

CircularSlider(value: $sliderValue, in: 0...100) {
				Text("\(Int(sliderValue1))")
		}
    .tint(LinearGradient(colors: [.red, .orange, .yellow], startPoint: .top, endPoint: .bottom))

Adding Haptic Feedback

Add haptic feedback for a tactile user experience:

CircularSlider(value: $sliderValue, in: 0...100)
    .hapticFeedback(.medium)

Accessibility Customizations

Accessibility support is already enabled for CircularSlider. However, you can further enhance it by adding descriptive accessibility properties:

CircularSlider(value: $sliderValue, in: 0...100)
    .accessibilityValue("75 percent", hint: "Adjust the temperature setting", label: "Temperature Control")

This modifier allows you to define a custom value, hint, and label for assistive technologies like VoiceOver.
