Xamarin.Forms iOS error Selector name found in current argument registers: configureAnimation:forLay

Hello,

I have been experiencing a problem with my Xamarin Forms application when deploying it on iOS, where it crashes suddenly while I'm using it.

I noticed that the crash happens mostly when I'm:

• working with the multiple pickers (filling some form data)
• going through pages reasonably fast (it's a questionnaire, so users are supposed to navigate forward kind of fast).

This is some portions of the Crash report I captured on HockeyApp:

I also noticed that this crash only happens to me when using OS 10.3 I updated my Xamarin.Forms to 2.3.4.247 but nothing changed.

This is the Native stacktrace i got on visual studio 2017 when debugging on a Simulator

And this is a little portion from the crash log of a Mac on which the simulator is running (the thread that crashed, the log is very long):

Any ideas about the reason of this behavior? or how to deal with it?

Thank you.
