Charts framework not usable in a Swift class added to an Objective C project

[indieshack]

I've at Last managed to install the Charts Framework into my Objective C project with no compile issues, but it does NOT work correctly when the Charts API is used from a SWIFT class that's been added to the Objective C project. Any ideas for how to fix this?

Hmm. No idea. Ill look into it. Do you happen to have an example Xcode project I could look at before I try it myself.

I just tried this and it works. My guess is that you are passing the wrong types of data to the chart.
