What did you do?

In Xcode 15, I conformed ChartViewDelegate to assign it to LineChartView.

What did you expect to happen?

LineChartView works fine with no warning.

What happened instead?

The following warning is displayed on the implemented functions.

Main actor-isolated instance method 'chartValueSelected(_:entry:highlight:)' cannot be used to satisfy nonisolated protocol requirement
