XIB files in SPM couldn't find Swift classes due to name mangling differences between CocoaPods and SPM, causing:
```
Unknown class _TtC41SwiftWarplyFramework_SwiftWarplyFramework40MyRewardsBannerOffersScrollTableViewCell in Interface Builder file.
*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UITableViewCell 0x105f2d060> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key collectionView.'
```
## Solution
Added explicit `@objc(ClassName)` attributes to all cell classes to provide stable, predictable class names for XIB file instantiation.
