Sample

We have using Syncfusion SfPicker component in Xamarin.forms platform. It work fine in all iOS simulator and devices except iPhone X device and simulator. We have used the picker in a PopUp page. On Clicking the background of the popup page, we get exception in native UITableView datasource.
 
In Native iOS SfPicker base class is UIPickerView 
 
Exception detail:
 
Foundation.monoTouchException
Objective-C exception thrown.Name:NSInternallnconsistencyException
Reason:UITableView datasource is not set.
 
Replication procedure:
1)Run the sample in iPhone X
2)Click the Header to open Picker page.
3)SfPicker will be visible
4)Click out side to navigate other page.
 
Exception occur only on iPhone X
 
We have also attached the exception screenshot image and sample for your reference.

I can reproduce this using the sample -- I'm wondering if you only experience this using the SfPicker, or if there's a scenario where you can reproduce the same error with the Forms Picker? I'll leave this as confirmed for now but if this is only on the SfPicker side of things then it may or may not be a problem that lies there.
Comment 3 Paul Anderson 2017-11-15 03:50:08 UTC
The Issue occurs only in Xamarin.Forms iOS version and only with iPhone X simulator and device. The same is working fine in Xamarin.iOS which is the base implementation and using renderer support has been provided to forms. Also we cannot reproduce it with Forms Picker as it will be like a dialog appearing but SfPicker is directly added to PopUp page and only the page acts like a dialog. Also in further debugging on closing the Forms PopUp Page for iPhone X alone LayoutSubViews() gets called which leads to the exception.

Do we have an ETA when this will be fixed - this bug prevents us moving forward with Syncfusion and targeting iPhone X.

@Paul DiPietro  - Seeing this also - iPhoneX device and simulator running 11.x

Tested now with latest XF 2.5.0.121934 and get this exception all the time.
Do not see this exception under any other iOS device other then iPhone X.

Do we have a XF build on alpha that fixes this ?
