We covered a huge amount of ground in this project, and you’ve learned about paths, shapes, strokes, transforms, drawing groups, animating values, and more. Not everyone will want to use all those features, and that’s OK – hopefully you have a clear idea of which parts interested you the most, and have some good coding experience with them.
If you combine your new-found drawing abilities with all the animation functionality we covered back in project 6, I hope you’re starting to realize just how much power and flexibility SwiftUI gives us. Yes, you can of course create whole apps using
NavigationView, and similar, but you can also build completely custom user interfaces that look fantastic and are just as fast.
Anyone can sit through a tutorial, but it takes actual work to remember what was taught. It’s my job to make sure you take as much from these tutorials as possible, so I’ve prepared a short review to help you check your learning.
One of the best ways to learn is to write your own code as often as possible, so here are three ways you should try extending this app to make sure you fully understand what’s going on.
Arrowshape made from a rectangle and a triangle – having it point straight up is fine.
ColorCyclingRectangleshape that is the rectangular cousin of
ColorCyclingCircle, allowing us to control the position of the gradient using a property.
