Question 1

How do I customize the animation speed in ExpandingCollection?

Accepted Answer

The README doesn't provide direct APIs for animation speed; you'd need to modify the underlying animation parameters in the ExpandingViewController subclass or extend the library, which requires diving into the source code.

Question 2

Can I use ExpandingCollection with SwiftUI?

Accepted Answer

No, it's built for UIKit only. To use it in SwiftUI, you'd need to wrap it in a UIViewControllerRepresentable, adding complexity and potential performance overhead.

Question 3

What's the difference between ExpandingCollection and a custom UICollectionView layout?

Accepted Answer

ExpandingCollection provides a ready-made, animated card interface with peek/pop interactions, saving development time, while a custom layout offers more control but requires writing all animation and transition code from scratch.

Question 4

How to handle dynamic content in ExpandingCollection cells?

Accepted Answer

You can update cell data by implementing UICollectionViewDataSource methods in your ExpandingViewController subclass, but ensure to manage state carefully during animations to avoid glitches.

Question 5

Is ExpandingCollection compatible with both CocoaPods and Carthage?

Accepted Answer

Yes, the README shows support for CocoaPods and Carthage via Podfile or Cartfile entries, making dependency management flexible for most iOS projects.

Question 6

How to change the card size in ExpandingCollection?

Accepted Answer

Set the itemSize property in your ExpandingViewController's viewDidLoad, as specified in the README, but note that height must account for both open and closed states, which can be tricky to adjust.

Question 7

ExpandingCollection or manual animations: which is better for performance?

Accepted Answer

ExpandingCollection optimizes animations with built-in caching, but for highly customized or lightweight needs, manual animations might offer better control and potentially lower overhead on older devices.
