Refactoring Newsfeed & Open Sourcing IGListKit

Earlier this year, Instagram released a rewritten newsfeed on iOS. When rebuilding its feed, the team undertook a huge refactor of its most-used feature, all while other teams were actively working on it. From this refactor, they learned a lot about how to build a highly-performant and stable feed, and through this work built a new open source project called IGListKit.

Come learn about how and why the Instagram team took on rewriting their iOS feed from the bottom up, see what it takes to ship a successful refactor, and learn about their new open source project being released.
