Over the air (OTA) installation fails for iOS8 app using itms-services URL

Question

For all prior versions of iOS, I\'ve used the itms-services:// URL to install test iOS apps over the air (OTA). Now, all my devices with iOS8 fail when trying to install app

Answer 1

We had the same problem. Our cause was that TestFlight had installed the bundle previously. It seems that TestFlight has (had) a profile installed, and only it could update the apps, even if they were uninstalled and deleted.

A workaround was to add some suffix to the bundle identifier in the plist.

This of course caused another problem, that a secondary icon was showing until download was complete and the IPA was unpacked and matched with the app already on device.

BIG NOTICE: This is only a problem with iOS8, so you better check the user-agent during the download. It will be itunesd and will contain the exact iOS version.
