Reports are coming in from readers that selected newly updated apps from the iOS App Store and Mac App Store are refusing to work following the update.
Affected apps are either refusing to load altogether or crashing on the startup screen.
Instapaper creator Marco Arment reports that he was "deluged by support emails and Twitter messages from customers," who could no longer open his app following the release of the new 4.2.3 update.
"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," writes Arment on his personal blog.
When updating apps using iTunes some users are seeing a dialog box displaying "error 8324" or "error 8326".
The following is a partial list of apps that Arment believes to be affected:
- Readdle Scanner Pro
- Angry Birds Space HD Free
- Gaia GPS
- Flick Soccer
- iBike Moto
The full list of apps affected has grown to well over 70.
I can confirm that I am experiencing this problem with both Instapaper and Angry Birds Space HD Free apps.
It seems that the only fix for those who have corrupted copies of an app is to delete it and reinstall a good copy. However, it seems that both the iOS App Store and Mac App Store are still serving corrupted apps, so you might need to wait until good copies are released.
Given that this problem appears to be ongoing, it may be a good idea to hold off updating any apps until Apple fixes this problem --- especially any apps that are critical to your workflow.
You can delete apps on iOS devices by tapping and holding the screen until the icons start to "jiggle" then tapping the red "X" in the top-left corner to delete. Press the "Home" button to return them to the normal "unjiggling" state.
Apple has not responded for comment to ZDNet, but will update the post if I hear back.
UPDATE: A long-time Hardware 2.0 reader/tipster offers this temporaty workaround.
Since I have three apps that have stopped working, and since the developers seem powerless to fix this issue, I decided to give Apple tech support a call and see what they had anything to offer.
While officially Apple's official position is that apps are the responsibility of the developers, the support rep did have this suggestion. It will only work if you updated the app OTA -- Over The Air -- and haven't connected it to iTunes since making the backup.
- Delete the app off the iPhone/iPad
- Connect the device to iTunes
- Go into the Apps tab and add the app to the device manually
- iTunes will now copy an old copy of the app back to your iOS device -- it's rather an ugly hack but it can help get that must-have app back working
