DatePicker and TimePicker not working on iOS

[yuv4ik]

Hello,

It seems like the DatePicker and TimePicker not working as expected on iOS 11.0 and 9.3.
By 'not working as expected' I mean that it's not showing the pickers and it seems like the focus trick is not working properly.

Seems like the solution is quite simple:
Device.BeginInvokeOnMainThread(() =>
{
EntryField.Unfocus();
Picker.Focus();
});

Have to ensure focus related stuff execution on the Main thread.

I created a pull request.
