Plot Math Functions With Swift Charts LinePlot

This article explains how to use the new LinePlot and AreaPlot APIs introduced in Swift Charts with iOS 18 to plot mathematical functions directly, without needing to pre-sample data into an array. It covers the benefits of this approach for smooth curves like probability density functions, provides a complete code example for plotting a normal distribution, and discusses availability across Apple platforms. The article also notes the need for availability checks for older OS versions and demonstrates how to handle undefined or infinite values in function closures.
