ChartDataSet文件报错，报错信息：

Type 'ChartDataSet' does not conform to protocol 'RangeReplaceableCollection'

Unavailable instance method 'replaceSubrange(_:with:)' was used to satisfy a requirement of protocol 'RangeReplaceableCollection'

解决方案：

// MARK: RangeReplaceableCollection

extension ChartDataSet: RangeReplaceableCollection方法里补充

public func replaceSubrange<C>(_subrange: Swift.Range<Int>, with  newElements: C) where C: Collection, ChartDataEntry == C.Element{

}
