If you want simple shapes to use in your app, you can create them directly then just color and position them as needed.
For example, if you wanted a 200x200 red rectangle, you would use this:
Rectangle() .fill(Color.red) .frame(width: 200, height: 200)
Similarly, if you wanted a 50x50 blue circle you would use this:
Circle() .fill(Color.blue) .frame(width: 50, height: 50)
