Creating Custom Graphics

In this chapter, we will examine how to style your apps with custom graphics in SwiftUI. We will first examine how to create custom modifiers. We will explain how to use Core Graphics within the Canvas view. Then, we will explain how it is possible to use CALayers, and core animation layers in SwiftUI, and then, finally, we will introduce you to CustomLayout. The purpose of this chapter is to be able to style the graphical style of our views with more freedom than what is allowed by the default styling, allowing for more creative liberty, and, when possible, doing that in the most effortless way possible.

In this chapter, we’ll be covering the following topics:

  • Creating custom modifiers
  • The Canvas
  • CALayers in SwiftUI
  • CustomLayout
