A simple toolkit for displaying and manipulating SVGs on iOS and macOS in a performant manner.

The goal of this project is not to be a fully compliant SVG parser/renderer. But rather to use SVG as a format for serializing CG/UIPaths, meaning it only supports SVG features that can be represented by CG/UIPaths.

Thoroughly documented.

• Support for SVG elements: path, line, polyline, polygon, rect, circle, ellipse
• Support for SVG named colors.
• Fully working iOS and macOS demos.
• Straightforward API for typical SVG rendering as a UIImageView/NSImageView or CALayer subclass.
• Access every shape within your SVG as a CGPath for more fine-grained manipulation.

Add this to your Podfile:

pod 'PocketSVG', '~> 2.0'

Then run pod install

Add this to your Cartfile:

github "pocketsvg/PocketSVG" ~> 2.0

Then run carthage update

Drag and drop PocketSVG.xcodeproj into your Xcode project. In your project settings, add PocketSVG.framework in Link Binary With Libraries.

let url = Bundle.main.url(forResource: "tiger", withExtension: "svg")!
let svgImageView = SVGImageView.init(contentsOf: url)
svgImageView.frame = view.bounds
svgImageView.contentMode = .scaleAspectFit
view.addSubview(svgImageView)

Output

Note: By default, SVGLayer has shouldRasterize set to YES when running on iOS. If you need to animate changes to the layer's transform you might want to reset that to NO.

view.backgroundColor = .white

let svgURL = Bundle.main.url(forResource: "tiger", withExtension: "svg")!
let paths = SVGBezierPath.pathsFromSVG(at: svgURL)
let tigerLayer = CALayer()
for (index, path) in paths.enumerated() {
    let shapeLayer = CAShapeLayer()
    shapeLayer.path = path.cgPath
    if index%2 == 0 {
        shapeLayer.fillColor = UIColor.black.cgColor
    }
    else if index%3 == 0 {
        shapeLayer.fillColor = UIColor.darkGray.cgColor
    }
    else {
        shapeLayer.fillColor = UIColor.gray.cgColor
    }
    tigerLayer.addSublayer(shapeLayer)
}

var transform = CATransform3DMakeScale(0.4, 0.4, 1.0)
transform = CATransform3DTranslate(transform, 200, 400, 0)
tigerLayer.transform = transform
view.layer.addSublayer(tigerLayer)
