when I run my app, the slider doesn't pick the constraints assigned to it and looks totally out of place, unless I touch one of the knobs and make the gesture of moving them. When I do that touch in the knob, the constraints load and the sizing gets corrected. Am I doing something wrong or is that some problem related to the rangeslider itself??

How can I get this to show up in a storyboard? I attempted to mark the RangeSlider class as IBDesignable and assign it to a UIView however at runtime the control doesn't render.

Hey, great work with the slider! I used it without any problems with Swift 2.2, but then I migrated to Swift 3 and now I have some small problems, it does not compile because of those lines:

override func layoutSublayersOfLayer(_ layer: CALayer) { super.layoutSublayersOfLayer(layer) updateLayerFrames() }

the error states this function does not override anything in the superclass...

I modified this library on a project of mine in order to change the thumb border width and color to create the style below. Thought it might be helpful to have included in the library as well.

The newValue variable contains the oldValue and not the new one. To access the new value, we just have to call the variable name.

New in latest version of Swift maybe ?

With the release of Xcode 10.2, you can no longer compile anything from Swift 3. There wasn't much code change needed, just configuration. The configuration updates were the automatic suggested updates from Xcode.

this is my code. and i only see gray line

` let sliderCover = UILabel() let sliderMainView = UIView() var slider = RangeSlider()

@objc func priceAction(){
    
    
    let priceLabelSTR = UILabel()
    let priceTo = UILabel()
    let priceFrom = UILabel()
    
    let priceToLabel = UILabel()
    let priceFromLabel = UILabel()
    
    
    let PriceSubmitButton = UIButton()
    let PriceCancleButton = UIButton()
    
    

   
    PriceLabel.backgroundColor = Colors.lowBlue
    PriceLabel.textColor = .white
    
    view.addSubview(sliderMainView)
    sliderMainView.addSubview(slider)
    sliderMainView.addSubview(priceLabelSTR)
    sliderMainView.addSubview(priceFrom)
    sliderMainView.addSubview(priceTo)
    sliderMainView.addSubview(priceToLabel)
    sliderMainView.addSubview(priceFromLabel)
    sliderMainView.addSubview(PriceSubmitButton)
    sliderMainView.addSubview(PriceCancleButton)

    view.addSubview(sliderCover)

    
    
    sliderCover.frame = view.frame
    sliderCover.alpha = 0.5
    sliderCover.backgroundColor = UIColor.black
    
    
    sliderMainView.translatesAutoresizingMaskIntoConstraints=false
    sliderMainView.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: 0).isActive=true
    sliderMainView.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 0).isActive=true
    sliderMainView.heightAnchor.constraint(equalTo: view.heightAnchor, multiplier: 0.3).isActive=true
    sliderMainView.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: 0).isActive=true
    sliderMainView.backgroundColor = .white
    view.bringSubviewToFront(sliderMainView)
    sliderCover.bringSubviewToFront(sliderMainView)
    
    
    
    priceLabelSTR.translatesAutoresizingMaskIntoConstraints=false
    priceLabelSTR.trailingAnchor.constraint(equalTo: sliderMainView.trailingAnchor, constant: -16).isActive=true
    priceLabelSTR.topAnchor.constraint(equalTo: sliderMainView.topAnchor, constant: 6).isActive=true
    priceLabelSTR.textColor = Colors.lowBlue
    
    
    slider.translatesAutoresizingMaskIntoConstraints=false
    slider.trailingAnchor.constraint(equalTo: priceLabelSTR.trailingAnchor, constant: 0).isActive=true
    slider.leadingAnchor.constraint(equalTo: sliderMainView.leadingAnchor, constant: 10).isActive=true
    slider.topAnchor.constraint(equalTo: priceLabelSTR.bottomAnchor, constant: -6).isActive=true
    slider.bottomAnchor.constraint(equalTo: sliderMainView.bottomAnchor, constant: 0).isActive=true

    //slider.backgroundColor = Colors.yellow
    slider.addTarget(self, action: #selector(sliderAction(_:)), for: .valueChanged)
    slider.upperValue = 1000
    slider.lowerValue = 1000
    slider.maximumValue = maxPrice
    slider.minimumValue = minPrice
    slider.curvaceousness = 0
    slider.frame = sliderMainView.frame`

}

'RangeSlider' has different definitions in different modules; first difference is definition in module 'WARangeSlider.Swift' found property name 'lowerValue'

Specifying a range 0-24, the thumb stops at 22, and can't pull it up to 23.

The other issue is: how to set the minimum range size? It seems to be fixed to 1. I'd need to set it to 0 so that the thumbs could be fully overlapped.

Thanks a lot, David

Hello, rangeSlider.minimumValue = 0 rangeSlider.maximumValue = 7 rangeSlider.lowerValue = 0 rangeSlider.upperValue = 7

I'm trying to avoid from user to scroll to same lower & upper values (e.g 7 & 7) is it possible to set minimum value range? (make the user scroll till value:6) Thanks, Ofir.

My first test of the repo was on the XR simulator. Horrible delays in starting the drag motion. Doesn't show up on random testing on older (ie iphone8) simulators.

when I tried to update the value of minimum value and maximum value of the RangeSlider manually, it shows a error like Assertion failed: RangeSlider: minimumValue should be lower than maximumValue and I have attached my code as well,

var sliderReference = RangeSlider() ... sliderReference.maximumValue = maximumPrice sliderReference.minimumValue = minimumPrice`
