How do I make iOS Charts LineChartView show as a spline (smooth line chart)?

Question

I'm new to iOS Charts, but I've figured out how to do many things with it. One thing I can't figure out (or find anywhere) is how to show the LineChartView as a spline instead of distinct lines to each data point. I want it to be smooth and flowing, not jagged.

Set the mode in the LineChartDataSet:

let dataSet = LineChartDataSet(values: entries, label: "Foo")
dataSet.mode = .cubicBezier
