I made this playground to attend WWDC18: I tried to explain in a simple and interactive way the basics for the sketching of a face.
Once you have chosen the parameters to give to your face and you have tapped on Run My Code,
the playground will help you make your drawing through guidelines.
- UIKit, I used UIBezierPaths to define the path of different guidelines;
- PaintCode, with this vector drawing app I could obtain the right values to build the UIBezierPaths as I wanted;
- CoreAnimation, I added CABasicAnimations to CAShapeLayers in order to simulate drawing animations;
- CoreGraphics, I used the current CGContext for the implementation of a drawing area for the user.
Here it is a video of my Playgroundbook
