TLDR

Google has fixed an issue in Google Analytics for Firebase iOS+ that caused thousands of iPhone and iPad apps to crash at launch. Google said the problem began Monday at 5:41 p.m. PDT and fully rolled out a fix by 7:52 p.m., with no SDK updates required from developers. Because of caching, some app instances could continue crashing for up to four hours after the rollout completed. Reporting on the incident said the fault was on Google’s side and involved an incorrectly formatted the available reporting received by the SDK. Reports also said some developers saw crash counts spike dramatically, including into the tens of thousands. Affected apps should now be working normally again.

A Google Analytics for Firebase issue caused thousands of iOS apps to crash on launch before Google rolled out a fix later the same evening.

Featured Source

Google said the issue began Monday at 5:41 p.m. PDT and that it had fully rolled out a fix by 7:52 p.m. PDT, with no SDK updates required from developers, as summarized in a Google engineer’s timeline highlighted by 9to5Google. Google also said that, because of caching behavior, some app instances could continue crashing for up to four hours after the fix was completed.

That meant the problem could linger temporarily even after Google had addressed the underlying issue. Later coverage said affected apps should no longer be crashing, and no action was required from developers (MacRumors, 9to5Google).

What went wrong

Reporting on the incident said the fault was on Google’s end and involved an incorrectly formatted payload received by the SDK (9to5Google).

That helps explain why so many unrelated apps appeared to fail around the same time. Firebase is widely used across iPhone and iPad apps for analytics and backend tooling, so a problem in a shared Google component affected a large number of apps (Android Authority).

How widespread it was

Reports described the impact as unusually broad. Android Authority wrote that the bug caused thousands of iOS apps to start crashing and said some apps saw crash numbers more than 5,000 times higher than normal. Later reporting said some developers were seeing tens of thousands of crashes, and in some cases more, from users of a single app (Android Authority, 9to5Google).

The timing also appears to have created confusion because the issue started shortly after Apple released iOS 27.0.1. But MacRumors reported that the overlap was coincidental, noting that apps were also crashing on other iOS versions, pointing back to Firebase rather than Apple’s update.

For users, the practical outcome is simple: apps affected by the Firebase analytics issue should now be back to normal.
