Keyboard Extension Memory Issue

I've created a new Xcode project and I added a new Custom Keyboard Extension Target by using Editor > Add Target > Custom Keyboard Extension.

Then, I ran that default templated keyboard on my real device (not happened in simulator). And I opened Instruments > Allocations application to profile memory allocations of extension.


When I was trying the keyboard on WhatsApp, I've noticed that number of Persistent ViewController objects were increased while hide/unhide the keyboard by tap on the outside of the keyboard and tap input area.


Number of Persistent KeyboardViewController:

2 -- hide -- > 1 -- show -- > 3 -- hide --> 2 -- show --> 4 (increasing)

I was trying the keyboard on iOS Messages app too. And there was no duplication.

1 -- hide --> 0 -- show --> 1 -- hide --> 0 ( its ok )

Do u have any idea about this issue ? Why WhatsApp application duplicates the keyboard extension viewController.

Did you manage to find out an issue?

Hi were you able to fix this. We are having the same issue and this is driving us crazy.

Any solution for this issue?
