35.4 Drawing Custom Paths and Shapes
The shapes used so far in this chapter are essentially structure objects that conform to the Shape protocol. To conform with the shape protocol, a structure must implement a function named path() which accepts a rectangle in the form of a CGRect value and returns a Path object that defines what is to be drawn in that rectangle.
A Path instance provides the outline of a 2D shape by specifying coordinate points and defining the lines drawn between those points. Lines between points in a path can be drawn using straight lines, cubic and quadratic Bézier curves, arcs, ellipses and rectangles.
In addition to being used in a custom shape implementation, paths may also be drawn directly within a view. Try modifying the ContentView.swift file so that it reads as follows:
struct ContentView: View {
var body: some View {
Path { path in
&...
