Hi! I wrote the article.

Excellent question! You are right, we definitely did not choose to implement it in SwiftUI because it’s easier than it would have been with UIKit.

Our main concern was to build a future-proof solution for our SDK customers. Apple has repeatedly made clear that they consider SwiftUI the future of UI development for their platforms.

Even though we were not able to implement the whole timeline experience without falling back to UIKit techniques, we think the result was worth the extra effort. For example, it is very flexible in terms of appearance and theming, including sizes, colors, animations, and behavior.
