Performance impact

[snoozemoose]

I'm experiencing severe performance reduction in UICollectionViews, even if no cells (or subviews) are styled at all. I'm guessing that this is caused by the swizzling of func willMove(toSuperview newSuperview: UIView?) that will check every view ever moved to a parent to see if a style should be applied? Any input, past experience, or other help of how to work around the performance reduction would be highly appreciated!
