Non-animated updates shouldn't wait until the next turn of the run loop

[Janum Trivedi]

let v = UIView()
v.bounds.size = CGSize(width: 50, height: 50)
v.animator.scale = CGPoint(x: 0.5, y: 0.5)

print(v.frame.size)

This will print (50, 50) instead of (25, 25) until the next turn of the run loop. We shouldn't require the display link to fire to update things non-animatedly.
