Question 1

How to use CrownControl with a UICollectionView?

Accepted Answer

CrownControl works with any UIScrollView subclass, so for UICollectionView, bind CrownAttributes to the collection view's scroll view property. Ensure you call spinToMatchScrollViewOffset in scrollViewDidScroll to sync scrolling, as shown in the Quick Usage example.

Question 2

CrownControl vs native scroll indicators: which is better for UX?

Accepted Answer

CrownControl offers precise, thumb-friendly scrolling with haptic feedback and repositioning, ideal for long documents or lists. Native scroll indicators are simpler and more familiar but less customizable and require more thumb movement. Choose based on app complexity and user interaction needs.

Question 3

Can CrownControl be customized for dark mode in iOS?

Accepted Answer

Yes, use the Style attributes to set background and foreground colors or gradients that adapt to dark mode. For example, configure backgroundStyle.content with dynamic colors from UIColor, but note that automatic dark mode switching isn't built-in—you must handle trait collection changes manually.

Question 4

What's the performance impact of adding CrownControl?

Accepted Answer

CrownControl is lightweight and uses standard UIKit components, so performance overhead is minimal. However, excessive haptic feedback or complex gradients in the Feedback and Style sections could affect battery life on older devices.

Question 5

How to make CrownControl accessible for VoiceOver?

Accepted Answer

The README doesn't cover accessibility, so you'll need to implement it manually. Set accessibility traits and labels on the crown view, and consider providing alternative scrolling methods, as CrownControl might not be fully accessible out-of-the-box.

Question 6

Is CrownControl compatible with SwiftUI?

Accepted Answer

No, CrownControl is built with UIKit and requires UIViewControllers or UIViews. To use it in SwiftUI, wrap it in a UIViewRepresentable, but this adds complexity and may limit some interactive features like force touch.
