Google Firebase issue caused widespread iPhone app crashes

Thousands of iPhone and iPad apps crashed on Monday after a problem with Google Analytics for Firebase led to launch failures. The disruption began late in the day and was traced to an incorrectly formatted payload from Google's systems, causing apps that integrated Firebase to fail. Google quickly rolled out a server-side fix, resolving the issue without requiring any updates from developers. Affected apps should now be working again.

• Apps with Firebase integration crashed on launch
• Problem started Monday evening Pacific Time
• No app or SDK update was needed to resolve the issue
• Some users still saw crashes for up to four hours after fix
• Timing unrelated to any specific iOS version
