Can't suspend the ongoing drag

[ionsilviumihai]

There is a case when the user is dragging the chart (on X-axis) using two fingers and I end up having a nasty UI bug.
I want to suspend all touch events on the chart at a certain point. I have an ongoing drag event on the chart that I can't force cancel.

I tried:

• chartView.dragEnable = false
• chartView.isUserInteractionEnabled = false
• UIApplication.shared.endIgnoringInteractionEvents()

All these are disabling the interaction that starts in the future but is not invalidating the touch happening on the chart at the moment the instruction is called.

On Android, the trick is perfectly done by using chartView.setTouchEnabled(false), but the iOS Charts seems that is not supporting this.

How should I handle this?

I assume you should check if you can invalidate the gesture itself, like checking the state and hijack something to stop it
