Google Resolves Bug Causing iPhone Apps to Crash

An unexpected issue with Google’s Firebase platform caused a significant number of iPhone apps to crash overnight, but a solution has already been implemented.

If you were experiencing crashes on your iPhone or iPad last night, rest assured that you were not alone. Google acknowledged that a problem with Analytics for Firebase was the culprit behind the crashes that occurred when users attempted to launch certain apps. The root of the issue was traced back to an error in the payload format for the SDK, which was on Google’s end.

It may come as a surprise that Google was behind a widespread iPhone crashing problem, but Firebase is a crucial tool for developers working on both Android and iOS platforms, integrated into numerous apps. The crash issue was beyond the control of developers and required intervention from Google. The impact was substantial, with some developers reporting tens of thousands of crashes – and in some cases, even more – from their app users.

Thankfully, Google has since confirmed that the necessary fix has been deployed. According to Nick Cooke, a software engineer at Google, the timeline of events unfolded as follows:

The issue with Google Analytics for Firebase iOS+ was first detected on Monday, September 28, 2026, at 17:41 US/PDT, resulting in crashes upon app launch due to a malformed payload received by the SDK.

The fix was fully implemented by Monday, September 28, 2026, at 19:52 US/PDT.

No action is required from app developers to implement this fix.

Due to caching mechanisms, some app instances may still experience crashes for up to 4 hours after the fix rollout. However, these lingering issues should resolve themselves automatically by September 28, 2026, at 23:52 US/PDT.

The crashing problems should now be resolved as the patch was fully deployed around midnight Pacific Time last night, without the need for any app updates. Affected apps should now be functioning correctly once again.

In conclusion, the issue with crashing iPhone apps caused by Google’s Firebase platform has been addressed, and affected apps should now be back to normal operation.
