I'm using SignaturePad component version 1.4.0.
Currently I'm using VS2015 + Shared project + Xamarin.iOS (In ther future i'll need it also for UWP & Android).
When I build with Debug configuration the SignaturePad works greate.
But if I build with Release or AppStore configuration the the SignaturePad doesn't render on the screen,
The view is completely blank.
So I went to the iOS project settings and noticed that "Optimize code" is checked on Release/AppStore and unchecked on Debug.
I unchecked it and now the SignaturePad works as expected while build with all of the configurations.
Maybe somebody can explain why?
It looks like a quick and dirty workaround
