This post is from the Activity iPhone Duo UIKit Q&A.
"How should our application's components (campaign cards, payment flows, bottom sheets) be displayed on iPad and Apple Duo?
Should we adapt our current iPhone-only design to iPad, or create separate layouts?
Should layouts work seamlessly during fold/unfold transitions on Apple Duo?
Can we reuse the same storyboards and XIBs, or do we need device-specific implementations?
Are Size Classes sufficient, or do we need custom breakpoints for these different screen sizes?"
