Final example doesn't show RadListView on iOS device

[fasterinnerlooper]

I am previewing this playground code on an iOS device: https://play.nativescript.org/?id=WhQU5V&v=341

When I log in and attempt to add items to the list, no items are displayed in the RadListView. I was running through the tutorial myself, but started getting this error about the listview: Warning: When used inside StackLayout with vertical orientation, RadListView should have an explicit height.

It looks like an update to the codebase is now causing a problem with the tutorial example code.
