How to round corners of this custom shape SwiftUI? - swift

Question

I used this tutorial to create a hexagon shape:
https://www.hackingwithswift.com/quick-start/swiftui/how-to-draw-polygons-and-stars
My goal is to try to round the corners of my hexagon shape. I know I have to use the path.addCurve somehow, but I cannot figure out where I need to do that. I am only getting weird results. Has anyone got an idea?
struct Polygon: Shape {
let corners: Int
let smoothness: CGFloat
func path(in rect: CGRect) -> Path {
guard corners >= 2 else { return Path() }
let center = CGPoint(x: rect.width / 2, y: rect.height / 2)
var currentAngle = -CGFloat.pi / 2
let angleAdjustment = .pi * 2 / CGFloat(corners * 2)
let innerX = center.x * smoothness
let innerY = center.y * smoothness
var path = Path()
path.move(to: CGPoint(x: center.x * cos(currentAngle), y: center.y * sin(currentAngle)))
var bottomEdge: CGFloat = 0
for corner in 0 ..< corners * 2 {
let sinAngle = sin(currentAngle)
let cosAngle = cos(currentAngle)
let bottom: CGFloat
if corner.isMultiple(of: 2) {
bottom = center.y * sinAngle
path.addLine(to: CGPoint(x: center.x * cosAngle, y: bottom))
} else {
bottom = innerY * sinAngle
path.addLine(to: CGPoint(x: innerX * cosAngle, y: bottom))
}
if bottom > bottomEdge {
bottomEdge = bottom
}
currentAngle += angleAdjustment
}
let unusedSpace = (rect.height / 2 - bottomEdge) / 2
let transform = CGAffineTransform(translationX: center.x, y: center.y + unusedSpace)
return path.applying(transform)
}
}
struct Hexagon: View {
#Environment(\.colorScheme) var colorScheme
var body: some View {
Polygon(corners: 3, smoothness: 1)
.fill(.clear)
.frame(width: 76, height: 76)
}
}

Haven't found a fix but this library does what I want:
