Provided examples contain bugs/glitches about transition

Hi @dkarbayev, thank you for submitting this, I really appreciate that you made the video which clearly demonstrates some issues.
We are currently a bit low on resources to address these right on (as goes for the other open issues 😬), but I will do my best to get time for it on our planning a.s.a.p.

/Pods/Transition/Transition/Classes/AnimationLayer.swift:37:42: Static var 'full' is internal and cannot be referenced from a default argument value

public init(range: AnimationRange = .full, timingParameters: AnimationTimingParameters, animation: @escaping AnimationFunction) {
    self.range = range
    self.timingParameters = timingParameters
    self.animation = animation
}

// Any idea how to fix this??? Thanks in advance.

@dkarbayev
I have addressed the built-in transition animations, which incorrectly removed the visible view when the transition was cancelled.
The glitches (jumps) that are particularly apparent in the ModaltransitionsExample oddly enough seem to be specific to iOS 11 – I first tried to reproduce on iOS 10 but without luck. The issue occurs when a UIViewPropertyAnimator is reversed and continued. Apparently this is an unaddressed regression since iOS 11: https://openradar.appspot.com/34674968
I have created a temporary "fix" that continues the animation by specifying a linear timing curve, instead of none (when none are specified, the originial timing parameters should be used). This seems to avoid the jumping in the animation.

I have adjusted the access level of that property, as well as some others. Please create a separate issue in the future such that related comments and actions stay organized.
