Thumb buttons issue when both overlap. about nhrangeslider HOT 5 OPEN

I noticed this is exactly the same issue that was closed AFTER i wrote it. However sometimes you want the sliders to touch with no gap. to indicate a single value.
Say u wanted to display range of money but you also wanted to allow a single value.
Can I achieve this with a gap greater than 0?
example
you want to search for a product that is a range is $0 - $100
but then you want to do another search for a product thats exactly $50
with the same control.
Can you still do that with say a gap of 1. Without it saying $50 - $51?

I tried gapBetweenThumbs = 1.0 and it still displayed the same problem.
Are you using gesture touches to slide each button?
If so maybe you can check the tap or drag and make sure that the number of objects below the touch is always 1 if its greater than 1 then only drag the max not both ?
Hope that makes sense.

I think i see the issue.
In the code below it can set both to highlighted even though you really only want to move one of them.

Since they're both highlighted the continueTracking method will move both depending on the direction of the drag instead of just one.

You could do 2 checks.

1. See if both are highlighted if so by default MAX should be highlighted unless #2
2. if MAX is highlighted but is at its MAX value then highlight MIN thumb.

override open func beginTracking(_ touch: UITouch, with event: UIEvent?) -> Bool {
previouslocation = touch.location(in: self)

    // set highlighted positions for lower and upper thumbs
    if lowerThumbLayer.frame.contains(previouslocation) {
        lowerThumbLayer.highlighted = true
    }
    
    if upperThumbLayer.frame.contains(previouslocation) {
        upperThumbLayer.highlighted = true
    }

///NEW
if upperThumbLayer.highlighted && lowerThumbLayer.highlighted{
if upperThumbLayer.maxPosition == maxValue {
upperThumbLayer.highlighted = false
}else{
lowerThumbLayer.highlighted = false
}
}
/////////
return lowerThumbLayer.highlighted || upperThumbLayer.highlighted
}

I tried it locally and verified this fixes the issue

override open func beginTracking(_ touch: UITouch, with event: UIEvent?) -> Bool {
previouslocation = touch.location(in: self)

    // set highlighted positions for lower and upper thumbs
    if lowerThumbLayer.frame.contains(previouslocation) {
        lowerThumbLayer.highlighted = true
    }
    
    if upperThumbLayer.frame.contains(previouslocation) {
        upperThumbLayer.highlighted = true
    }
	
	if upperThumbLayer.highlighted && lowerThumbLayer.highlighted{
		if upperValue == maximumValue {
			upperThumbLayer.highlighted = false
		}else{
			lowerThumbLayer.highlighted = false
		}
	}
    
    return lowerThumbLayer.highlighted || upperThumbLayer.highlighted
}
