Creates a discrete slider control that selects a stepped value from a bounded range.

[`init(_:symbolName:values:)`](/documentation/AVFoundation/AVCaptureSlider/init(_:symbolName:values:))

Creates a discrete slider control that selects a value from a list.

[`initWithLocalizedTitle:symbolName:minValue:maxValue:`](/documentation/AVFoundation/AVCaptureSlider/initWithLocalizedTitle:symbolName:minValue:maxValue:)

Creates a continuous slider control that selects a value from a bounded range.

[`initWithLocalizedTitle:symbolName:minValue:maxValue:step:`](/documentation/AVFoundation/AVCaptureSlider/initWithLocalizedTitle:symbolName:minValue:maxValue:step:)

Creates a discrete slider control that selects a stepped value from a bounded range.

[`initWithLocalizedTitle:symbolName:values:`](/documentation/AVFoundation/AVCaptureSlider/initWithLocalizedTitle:symbolName:values:)

Creates a discrete slider control that selects a value from a list.

### Handling interaction

[`setActionQueue(_:action:)`](/documentation/AVFoundation/AVCaptureSlider/setActionQueue(_:action:))

Sets the action to perform on the specified dispatch queue when the control’s value changes.

[`setActionQueue:action:`](/documentation/AVFoundation/AVCaptureSlider/setActionQueue:action:)
