Picker crashes silently in iOS
In debug mode, it happens most of the time. In release mode, it rarely happens.
Here is the logs:

I am also getting this error but only when I have more than ~50 options in the picker. It doesn't seem to have any hard limit but the more options you add, the more often it will crash with the above error.

Interesting, I tried to reduce the number of options but it didn't help :/
