IOS 9 - Keyboard displays package name as "(null)" when updating

Question

I have an iOS keyboard app extension that exists in the app store. Recently, while testing the effects of updating an application from version 1.0 to 1.1, I noticed that when I click and hold the globe icon on the standard iOS keyboard, my application name appears as (null) . Has anyone else experienced this? This can happen if I do not try to open the companion application before opening the keyboard after updating. If I open the companion app, it will usually disappear. I have added the image below.

Update: Using the iOS console, I noticed a log entry below:

 Oct 5 16:16:40 Sarangan-Balasubramaniams-iPad SpringBoard[48] <Warning>: Installed apps did change.

I apologize for the hard readable output, but you can see that iOS is looking for my plugin in the wrong way. He is looking for my old installation path, not a new one . My simple guess is that the iOS keyboard caches the list of other keyboards somewhere and does not update it to some other trigger.

Answer 1

I saw it too; This is a bug in iOS. You must send a radar to it.

Typically, you can fix the problem for an individual application by closing the application from the application switcher and opening it again.

Spotlight and Quick Reply, in my experience, will not allow the keyboard to rise until the device reboots, which also fixes the problem for all other applications.

For people who are still experiencing this in iOS 10+, make sure your Bundle Name matches your Bundle Display Name .
