Description

Hello,

I'm trying to use these charts on a TVOS app. Till now, I'm able to get the charts displayed using my datasets. But, I'm facing issues while trying to interact with them. For example, If I draw a bar chart,

  • On IOS, whenever I click on any bar, there is a click event that handles the necessary things
  • On TVOS, there is no such notification. This is correct as these events in TVOS has to be done with focus events like (didUpdateFocusInContext, etc).

Is there a way this can be done. I really appreciate if anyone can help me solve this issue.

Thanks, Bharat

Research direction
Investigate how the Charts library currently handles touch events on iOS (e.g., in ChartViewBase.swift). Research the tvOS focus engine (UIFocusEnvironment, UIFocusUpdateContext) and determine how to map iOS touch interactions to focus based interactions on tvOS. Check if there are any existing branches or discussions in the repository about tvOS support. Look at similar implementations in other iOS to tvOS ported libraries.
