Over the last couple days, iOS users have been noticing some quite unexpected issues with certain apps, crashing immediately upon launch. Instapaper developer Marco Arment started looking into the situation after some of his users complained about the app’s latest update, and discovered that Apple appears to be distributing corrupted updates through the App Store.
With iOS security measure in place to prevent the distribution of unsigned apps, it’s no wonder that these corrupted files refuse to execute, but how are they getting messed-up in the first place? Arment verified that the update he submitted to Apple runs as expected, so clearly something’s happening between when Apple gets its hands on these updates and when it puts them up for distribution.
In Arment’s case, Instapaper now seems to be updating just fine, but it’s unclear if this is because Apple took any steps to directly the situation, or if the bad data was in a cache somewhere that has since refreshed itself. That’s not the end of things, though, because there are a whole lot more apps that seem to be suffering from the same issue, including high-profile titles like Angry Birds Space.
We’ve yet to hear any official comment from Apple on the matter, but supposedly the issue only affects users in the US and UK. There are plenty of theories as to exactly what’s going wrong, and the only way past the issue for now seems to be deleting affected apps and then reinstalling once non-corrupted data finally becomes available on Apple’s servers.
