Airbnb's Host Passport feature enables hosts to introduce themselves to guests, fostering a more personal connection, through a delightful 3D animation experience on the iOS platform.
Résumé
The article discusses how Airbnb implemented the Host Passport feature in their iOS app, which allows hosts to introduce themselves to guests through an engaging 3D animation.
Key highlights:
- Airbnb opted to use UIKit for the passport animation, as SwiftUI did not have the necessary APIs for custom transitions and navigation patterns at the time.
- The complexity of the animation lies in coordinating multiple moving parts, such as rotating the passport around the left edge to achieve a page-turning effect, without disrupting other transforms.
- Airbnb used a compound view approach, with a front page and two inside pages, to create the impression of a book-like passport.
- To integrate the 3D animation with Airbnb's declarative animation framework, the team created a custom snapshot that could play the page flip animation alongside the shared element transition.
- Precise timing and easing functions were used to ensure a natural and delightful animation experience, with keyframes controlling the start and stop points of individual animations.
The article provides insights into the technical challenges and solutions involved in bringing the Host Passport feature to life on the iOS platform, showcasing Airbnb's attention to detail and commitment to delivering a seamless and engaging user experience.
