SVGView

SVG parser written in SwiftUI

Overview

The goal of this project is to bring the full power of SVG to Apple platforms. Our framework can parse SVG files and represent their content in SwiftUI. It provides you with the ability to not only render SVG files, but also add interactivity to them, handle user input and use SwiftUI to put your art into motion.

Usage

Get started with SVGView in a few lines of code:

struct ContentView: View {
    var body: some View {
        SVGView(contentsOf: Bundle.main.url(forResource: "example", withExtension: "svg")!)
    }
}

Customization

You can change various parameters for the nodes like this:

let circle = SVGCircle(cx: 30, cy: 30, r: 30)
circle.fill = SVGColor.black
circle.stroke = SVGStroke(fill: SVGColor(hex: "ABCDEF"), width: 2)
circle.onTapGesture {
    print("tap")
}

Interact with vector elements

You may locate the desired part of your SVG file using standard identifiers to add gestures and change its properties in runtime:

struct ContentView: View {
    var body: some View {
        let view = SVGView(contentsOf: Bundle.main.url(forResource: "example", withExtension: "svg")!)
        if let part = view.getNode(byId: "part") {
            part.onTapGesture {
                part.opacity = 0.2
            }
        }
        return view
    }
}

Animation

You can use standard SwiftUI tools to animate your image:

if let part = view.getNode(byId: "part") {
    part.onTapGesture {
        withAnimation {
            part.opacity = 0.2
        }
    }
}

Complex effects

SVGView makes it easy to add custom effects to your app. For example, make this pikachu track finger movement:

var body: some View {
    let view = SVGView(contentsOf: Bundle.main.url(forResource: "pikachu", withExtension: "svg")!)
    let delta = CGAffineTransform(translationX: getEyeX(), y: 0)
    view.getNode(byId: "eye1")?.transform = delta
    view.getNode(byId: "eye2")?.transform = delta

    return view.gesture(DragGesture().onChanged { g in
        self.x = g.location.x
    })
}

SVG Tests Coverage

Our mission is to provide 100% support of all SVG standards: 1.1 (Second Edition), Tiny 1.2 and 2.0. However, this project is at its very beginning, so you can follow our progress on this page. You can also check out SVGViewTests project to see how well this framework handles every single SVG test case.
