📒 Field Notes

This day covers Part One of Project 9: Drawing in the 100 Days of SwiftUI Challenge.

It focuses on several specific topics:

• Drawing: Introduction
• Creating custom paths with SwiftUI
• Paths vs shapes in SwiftUI
• Adding strokeBorder() support with InsettableShape

Drawing: Introduction

From the description:

In this technique project we’re going to take a close look at drawing in SwiftUI, including creating custom paths and shapes, animating your changes, solving performance problems, and more>

Creating custom paths with SwiftUI

For custom paths, the StrokeStyle constructor is one of your best friends. This gives us fine-grained control over many of the imporant properties that define path style:

public struct StrokeStyle : Equatable {

    public var lineWidth: CGFloat

    public var lineCap: CGLineCap

    public var lineJoin: CGLineJoin

    public var miterLimit: CGFloat

    public var dash: [CGFloat]

    public var dashPhase: CGFloat


    ...
}
