Exception while on iPad (iOS 12)

[Dawit]

I have used this control successfully on Android and iPhone (through Xamarin forms), but when my app is deployed on iPad (iOS 12) I keep getting this exception and a page containing this control wont even load. Please help.

System.NullReferenceException: Object reference not set to an instance of an object
  at Xamarin.Forms.Platform.iOS.EntryRendererBase`1[TControl].GetClearButtonTintImage (UIKit.UIImage image, UIKit.UIColor color) [0x00000] in <4c65493b0ca44a809e1174d1a41683bd>…}

Well, turns out the problem was not the Syncfusion control, but a bug in Xamarin.Forms where setting the ClearButtonVisibility and TextColor at the same time on Entry crashed the app. As described here:  

[Bug] NullReferenceException in EntryRenderer on iOS versions <14.X with ClearButtonVisibility.WhileEditing and non-default TextColor · Issue #14523 · xamarin/Xamarin.Forms (github.com)

I have wasted my and you guys time for nothing.

This is the third framework bug that I came across on Xamarin.Forms just this week. I am starting to despair.

Thank you for your help.
