By: Clark Wright Introduction These days, as the volume of data collected by companies grows exponentially, we’re all realizing that more data is not always better. In fact, more data, especially if you can’t rely on its quality, can hinder a company by slowing down decision-making or causing poor decisions. With 1.4 billion cumulative guest arrivals as of year-end 2022, Airbnb’s growth pushed us to an inflection point where diminishing data quality began to hinder our data practitioners. Weekly metric reports were difficult to land on time. Seemingly basic metrics like “Active Listings ..read more

How Airbnb adopted SwiftUI in our iOS app Bryn Bodayle When constructing an app’s user interface (UI), the choice of framework is incredibly important. The right UI framework can make an app feel smooth, responsive, even delightful, while a UI framework that doesn’t match an app’s needs can make it feel sluggish and broken. This principle extends to developer experience as well; a UI framework with well-designed APIs can enable engineers to express themselves fluently, efficiently, and correctly, while one with the wrong abstractions or inconsistent APIs can make engineers’ jobs more dif ..read more
