[Interest] Sample Code for Apple TV and Apple Watch Qt Garage demos at Qt World Summit 2016

[Mike Krus]

Apple Watch’s public API does not support UIKit so there’s no QPA plugin available. As Jake's demo shows, qtcore works fine for low level work like networking, but the UI must be done using native toolkits.


tvOS works fine. Widgets don’t build by default but can be enabled (they are unusable though).
Main issue (including for QtQuick) is due to how input works with the controller. Never got around to implementing some generic solution.

Please check the code in the planets-watchos directory of the sample planets-qml.
