SketchAFace Playgroundbook

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.

Technologies involved:

• 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.
