It looks like some of the apps in Apple’s App Store, which have been updated over the last couple of days are causing problems with users of the iPhone, iPad and iPod Touch.
The issue was first spotted by the developer of the Instapaper app, when an update to their app was released, which was working fine, but when users downloaded the app it started crashing.
Last night, within minutes of Apple approving the Instapaper 4.2.3 update, I was deluged by support email and Twitter messages from customers saying that it crashed immediately on launch, even with a clean install.
This didn’t make sense — obviously, Apple had reviewed it, and it worked for them. My submitted archive from Xcode worked perfectly. But every time I downloaded the update from the App Store, clean or not, it crashed instantly.
Lots of anxiety and research led me to the problem: a seemingly corrupt update being distributed by the App Store in many or possibly all regions.
And this is happening to other apps, not just Instapaper, updated in the last few days.
It looks like quite a few apps have been affected by the issue, Apple has yet to announce what the issue is and when it will be fixed.
