Avoid overriding preferredLayoutAttributesFitting in every auto-sizing UICollectionViewCell

[astralchen]

Hi QuickLayout team,

First of all, thank you for open-sourcing QuickLayout.
We’ve been using it successfully in a UIKit project and really like the declarative layout style and performance benefits.

We are currently using QuickLayout inside UICollectionViewCell with UICollectionViewCompositionalLayout, where:
• Cell width is fixed (fractionalWidth = 1.0)
• Cell height is dynamic and content-driven
• Layout uses .estimated(...) height

To make auto-sizing work, we currently need to override
preferredLayoutAttributesFitting(:) in every custom cell and call sizeThatFits(), for example:

override func preferredLayoutAttributesFitting(
    _ layoutAttributes: UICollectionViewLayoutAttributes
) -> UICollectionViewLayoutAttributes {
    var attrs = layoutAttributes
    let targetSize = CGSize(
        width: layoutAttributes.size.width,
        height: .greatestFiniteMagnitude
    )
    let size = sizeThatFits(targetSize)
    attrs.size.height = ceil(size.height)
    return attrs
}

This works well, but it becomes repetitive when many different cells use QuickLayout.

Question

Is there a recommended or built-in approach to:
• Avoid overriding preferredLayoutAttributesFitting(_:) in every cell?
• Or provide a shared / automatic integration for auto-sizing cells when using UICollectionViewCompositionalLayout?

For example:
• A base UICollectionViewCell provided by QuickLayout
• A protocol or helper API
• Or a way for @quicklayout to hook into the sizing lifecycle automatically

We understand this might be a UIKit limitation, but wanted to ask if there is an officially recommended pattern or future plan for this use case.

Thanks again for the great library!
