SliderControl

SliderControl is a small Swift Package aiming to recreate volume and track sliders found in Apple Music on iOS 16 and later.

Usage

SliderControl maintains an API similar to built-in UISlider. It has the same properties, like value and isContinuous. Progress observation is done the same way, by adding a target and an action:

sliderControl.addTarget(self, action: #selector(sliderValueChanged), for: .valueChanged)

Customization

There are a few properties to customize SliderControl's appearance:

• defaultTrackColor sets a track color for default state;
• defaultProgressColor sets a progress color for default state;
• enlargedTrackColor sets a track color for state when user actively changing the progress;
• enlargedProgressColor sets a progress color for state when user actively changing the progress.

The default value of enlargedTrackColor and enlargedProgressColor is nil, so the slider won't change color upon interaction in its default configuration. However, by setting different colors, you can configure the slider to change its appearance when user interacts with it. Here's an example:

sliderControl.defaultTrackColor = .quaternarySystemFill
sliderControl.defaultProgressColor = .tertiarySystemFill
sliderControl.enlargedTrackColor = .secondarySystemFill
sliderControl.enlargedProgressColor = .systemFill

By default SliderControl provides haptic feedback when value reaches lower and upper bounds. This behavior can be changed by setting providesHapticFeedback property to false. Types of haptic feedback can also be changed by subclassing SliderControl:

class MySliderControl: SliderControl {
    override var feedbackGenerator: UIFeedbackGenerator {
        return UINotificationFeedbackGenerator()
    }

    override func provideHapticFeedbackForMinimumValue() {
        (feedbackGenerator as? UINotificationFeedbackGenerator)?.notificationOccurred(.error)
    }

    override func provideHapticFeedbackForMaximumValue() {
        (feedbackGenerator as? UINotificationFeedbackGenerator)?.notificationOccurred(.success)
    }
}

RTL Support

SliderControl supports right-to-left languages.
