Error: "Assignment to readonly property" when updating charts data

[fazal07]

set1 = (LineChartDataSet *)_chartView.data.dataSets[0];
set1.yVals = yVals; ("Assignment to readonly property")
_chartView.data.xValsObjc = xVals; ("Assignment to readonly property")
[_chartView notifyDataSetChanged];

I am using charts library in objective-c project via cocoa-pod

[liuxuan30]

    /// the array of y-values that this DataSet represents.
    public var yVals: [ChartDataEntry]
    {
        get
        {
            return _yVals
        }
        set
        {
            _yVals = newValue
            notifyDataSetChanged()
        }
    }

maybe clean and rebuild.

@Property (nonatomic, readonly, copy) NSArray<ChartDataEntry *> * _Nonnull yVals;
in charts-Swift.h

You are not using master, but the latest release. We will make a release soon.
Wrapping up some stuff...
