Hello fellow ios devs.

After ios 13 we see lots of crashes related with keyboard. We only see this from crash reporting and can never reproduce it.

We suspect it is related to keyboard since there is referances to keyboard methods in call stack.

Here is the crash report coming from Fabric:

That's an extension, when you define custom keyboard. Is it your case ?

Class

UIInputViewController

The primary view controller for a custom keyboard app extension.

Declaration

class UIInputViewController : UIViewController

Overview

To create a custom keyboard, first subclass the UIInputViewController class, then add your keyboard’s user interface to the inputView property of your subclass. In Xcode, you can start a custom keyboard by choosing the Custom Keyboard target template.

Surprinsingly, when searching for UIInputViewController in XCode documentation, nothing is found.

What is YemeksepetiProd ? Is it the name of app ?

YemeksepetiProd is the name of the app. We don’t have any keyboard extension. It is related to system keyboard. When you open the keyboard and pause the app in view debugger it is in the view hierarch.

Hello myusuf6716,

Did you resolve this issue? I am facing the same crash, but can not reproduce it by myself.
