📒 Field Notes

This day covers Part Two of Project 9: Drawing in the 100 Days of SwiftUI Challenge. (Project 9 files can be found in the directory for Part One.)

It focuses on several specific topics:

• Transforming shapes using CGAffineTransform and even-odd fills
• Creative borders and fills using ImagePaint
• Enabling high-performance Metal rendering with drawingGroup()

Regarding the last point, I love how activating Metal via the drawingGroup modifier couldn't be more straightforward. But it's quite the Mjölnir. Use it sparingly -- and only as needed.
