Adding SKScene to a UICollectionViewCell lowers scrolling performance

Question

I am trying to add a SKScene with a simple animation to a UICollectionCell.

I've got my SKView setup in the .xib file of the collection view cell.

If I run it and scroll, it works as expected. But if I change to a different view controller (in a tab bar controller) that also uses those types of cells and start scrolling, it will get stuck.

Here's how I am adding the SKScene:

@interface MAPostCollectionViewCell ()

@property (strong, nonatomic) IBOutlet SKView *viewAnimation;
@property (strong, nonatomic) MAHeartAnimation *heartScene;

@end

@implementation MAPostCollectionViewCell

-(void)layoutSubviews{

    [super layoutSubviews];

    self.heartScene = [MAHeartAnimation sceneWithSize:self.viewAnimation.bounds.size];
    self.heartScene.scaleMode = SKSceneScaleModeAspectFill;

    [self.viewAnimation presentScene:self.heartScene]; 

}

@end

And I only trigger the animation if the user taps a button.

But for the scope of this question, the animation doesn't really matter, as I am not touching that button, just scrolling the UICollectionView.

It turns out you should not use SpriteKit and UIKit this way. Even though they are modular frameworks, they are not performant when using together this way. I ended up using UIKit for the animations that I wanted, by using CALayers.
