Answer 1

Using MTCircularSlider library

fileprivate var controlRadius: CGFloat {
     return min(bounds.width, bounds.height) / 2.0 - controlThickness
 }

See above this library uses min value from width and height.

So, You need to maintain your view width, because it's depend on minimum value of View. You can mange your view by leading and trailing according below screenshot

or either you can use by proportionalWidth constrain to 0.80 of your superview

And also set the trackAngle as below
