[Interest] Quick.Controls.Dialog embedded in QQuickView on iOS not visible

[lloyd konneker]

The same code on Linux and OSX shows the dialog.

My questions are: is that a bug, or do I need platform specific code, or 
is there another way, or is there a working example?

(Qt code announces that QQuickWidget is not supported on that platform, 
but it doesn't say that QQuickView is not supported.)

Platform is Qt5.4, PyQt5, Python3.4.2.
