I know that external change to center, bounds and transform will be ignored after UIDynamicItems init.

But I need to manually change the transform of UIView that in UIDynamicAnimator system.

Every time I change the transform, it will be covered at once.

So any idea? Thanks.

Another way to fix this (I think we should call it bug) is to override the transform property of the UIView used. Something like this:

override var transform: CGAffineTransform {
    set (value) {

    }
    get {
        return super.transform
    }
}

var ownTransform: CGAffineTransform. {
    didSet {
        super.transform = ownTransform
    }
}

It's a kind of a hack, but it works fine, if you don't use rotation in UIKitDynamics.
