ShapeEdit

ShapeEdit is a showcase for Advanced ScrollView, inspired by WWDC sample with the same name. ShapeEdit is build in SwiftUI, with exception of the scroll view, that is UIScrollView or NSScrollView under the hood.

ShapeEdit contains some shapes that can be interacted with on a fixed size canvas. You can:

• Drag shapes around;
• Resize shapes;
• Create new shapes;
• Change fill and stroke color;
• On macOS scroll view will autoscroll to follow the coursor;
• Zoom in/out;
• Delete elements from a context menu.

Note: this is just a prototype, it's not optimized for performance in any way and should be considered as a case study if you want to build something similar. You need Xcode 13 to run it. I developed it mainly for macOS, some features not working on iOS yet.
