swiftui - How to check whether one CGPoint is in a Shape?

Question

Let's say I have a Shape:

struct ShapeA: Shape {
    func path(in rect: CGRect) -> Path {
        Path { path in
            path.move(to: CGPoint(x: 100, y: 100))
            path.addQuadCurve(to: CGPoint(x: 110, y: 210), control: CGPoint(x: 130, y: 200))
            path.addQuadCurve(to: CGPoint(x: 180, y: 240), control: CGPoint(x: 140, y: 240))
            path.addQuadCurve(to: CGPoint(x: 200, y: 250), control: CGPoint(x: 150, y: 250))
            path.closeSubpath()
        }
    }
}

and a single CGPoint: CGPoint(x: 100, y: 100). How can I check whether this CGPoint is in the ShapeA (or any other Shape)

Answer 1

path.contains(point)

(Create path by calling .path(in rect:) on a ShapeA instance.)

For self-intersecting paths, you should look at the eoFill option for dealing with even-odd fill rules.
