Introduced at WWDC 2019, the SwiftUI framework gave the iOS community a lot to cheer about. An easy-to-use, declarative API written in Swift lets developers quickly build UI prototypes.

While we can leverage the Shapes protocol to build Bar Charts from the ground up, the same cannot be said about Line Charts. Thankfully, we’ve got the Paths structure to help us with that.

Using SwiftUI paths, which are similar to CGPaths from the Core Graphics framework, we can combine lines and curves to build beautiful logos and shapes.

Being true to the declarative way of writing UI, SwiftUI paths are built with a set of instructions. In the next few sections, we’ll discuss what that means.
