Case Study: Twitter achieves faster pre-release build adoption with Firebase App Distribution

How Twitter is using the new iOS SDK from Firebase App Distribution

Twitter’s release team needed a better way to keep internal testers on the latest pre-release build of its employee app, since email-based update notices were easy to miss and often left people running outdated versions. The team used Firebase App Distribution, specifically the new iOS SDK, to improve how testers received and installed nightly builds.

Firebase App Distribution added in-app update alerts and a smoother install flow, letting Twitter testers see whether they were on the latest version and update directly from the app, including an option to install after closing. As a result, Twitter reduced the time it took for the latest version to reach most users by nearly 20%, while making its testing process easier and less disruptive.
