Who Should Use SwiftSVG

SwiftSVG is not meant to be a a full SVG parser. The library supports the most common use cases of flat, solid color SVG elements. It supports grouping and transformations and can parse all path and shape elements.

The best use case for SwiftSVG is for flat icons that you may want to theme at runtime and have good control over. Think icons for your app, especially if you offer light and dark themes. The library can handle complex paths, and more importantly can handle them quickly, so you can use it to display many SVGs, just not every single use case. See the complex example in the examples app.

At this time, gradients are not supported, but this is high on the list of features to support next. Furthermore, text is not supported at this time, but shouldn't be too difficult to support. Animations are the last major category that isn't supported, and they probably won't be in the near future seeing Cocoa already provides rich support.

Finally, if you're looking to extend this project, that's another good reason to use SwiftSVG. A lot of work has been put into making the code as extensible and maintainable as possible and will continue to be a core feature of future updates. Fork the project and I hope you share your changes.

Swift version	SwiftSVG version
Swift 5.0	v2.3.0

Cocoapods:

pod 'SwiftSVG', '~> 2.0'

or Carthage:

github "mchoe/SwiftSVG" ~> 2.0

For projects currently using 1.x: SwiftSVG 2.x is a major rewrite of the library. For most use cases, you should be able to upgrade to 2.0 with little to no changes to your code. However, there are breaking changes that may affect your project. Most notably, the String extensions and the ability to parse single path string from a URL are deprecated.

Usage

UIView+SVG

The easiest way to create an SVG image is to use the UIView extension:

let fistBump = UIView(SVGNamed: "fistbump")     // In the main bundle
self.addSubview(fistBump)

Output:

Or you can add an SVG file to your Asset Catalog. You should add it as a Data Asset like this:

Then use the same initializer as above:

let cowboyHat = UIView(SVGNamed: "cowboyHat")     // In the asset catalog as a Data Asset
self.addSubview(cowboyHat)

Output:

You can also create a new UIView from a remote URL:

let svgURL = URL(string: "https://openclipart.org/download/181651/manhammock.svg")!
let hammock = UIView(SVGURL: svgURL) { (svgLayer) in
    svgLayer.fillColor = UIColor(red:0.52, green:0.16, blue:0.32, alpha:1.00).cgColor
    svgLayer.resizeToFit(self.view.bounds)
}
self.view.addSubview(hammock)

Output:

SwiftSVG provides the following UIView convenience initializers:

convenience init(SVGNamed: String, parser: SVGParser? = nil, completion: ((SVGLayer) -> ())? = nil)
convenience init(SVGURL: URL, parser: SVGParser? = nil, completion: ((SVGLayer) -> ())? = nil)
convenience init(SVGData: Data, parser: SVGParser? = nil, completion: ((SVGLayer) -> ())? = nil)

All of these initializers will parse a file located in the main bundle, a bundle of your own choosing, or on the web. It will parse the file asynchronously and optionally takes a completion block, passing a SVGLayer after parsing has been completed. Whether you pass a completion block or not, SwiftSVG will add it to the view's sublayers. If you want to change one of the layer's attributes, such as the fill color or resize it to fit a view, you can do that in the completion block

You can optionally pass an SVGParser object if you want to reuse the same parser for various SVG files or want to roll your own using a third-party XML parser. By default, SwiftSVG uses a subclass of Foundation's XMLParser using all the supported elements and attributes called NSXMLSVGParser. You can also optionally setup your own NSXMLSVGParser passing a SVGParserSupportedElements struct that will parse only the elements and attributes of your choosing.

There is also a convenience initializer to parse a single path string, which parses synchronously:

// Declaration
convenience init(pathString: String)

// Example
let triangle = UIView(pathString: "M75 0 l75 200 L0 200 Z")
self.addSubview(triangle)

Output:

CALayer+SVG

If you need a little bit more control over your parsed layer, you can use one of the CALayer convenience initalizers. You can make some changes to the parsed SVG layer, such as changing the fill color at runtime, and can add it to a layer of your own choosing. If you are dropping down to the CALayer level, it is assumed that you want more control and you must provide a completion block and you must add it to a sublayer to display it.

let svgURL = Bundle.main.url(forResource: "pizza", withExtension: "svg")!
let pizza = CALayer(SVGURL: svgURL) { (svgLayer) in
    // Set the fill color
    svgLayer.fillColor = UIColor(red:0.94, green:0.37, blue:0.00, alpha:1.00).cgColor
    // Aspect fit the layer to self.view
    svgLayer.resizeToFit(self.view.bounds)
    // Add the layer to self.view's sublayers
    self.view.layer.addSublayer(svgLayer)
}

Output:

You can create a new CALayer from URL or Data:

convenience init(SVGURL: URL, parser: SVGParser? = nil, completion: @escaping (SVGLayer) -> ())
convenience init(SVGData: Data, parser: SVGParser? = nil, completion: @escaping (SVGLayer) -> ())

SVGLayer

The layer that is passed in the UIView and CALayer completion blocks is an instance of SVGLayer which is a subclass of CAShapeLayer. Currently, SVGLayer adds the following capabilities:

A boundingBox property that is the minimum CGRect that encloses all subpaths. Good for scaling the layer to fit a view.
Overrides on some properties like the fill color, stroke color, and stroke width that applies that value on all sublayers.
An ability to create a copy of the SVGLayer, which is useful for caching.

Other Interfaces

CAShapeLayer & UIBezierPath Single Paths

In addition to the UIView extension that allows you to parse a single <path> d string, you can use the CAShapeLayer or UIBezierPath convenience initializers.

Output:

SVGView

Finally, SwiftSVG provides a UIView subclass that is IBInspectable. Simply add a view to your storyboard and use the SVGView subclass as your class name. Then put the name of your SVG file in your bundle in the IBInspectable property "SVGName"

Mutiple crash due to swift optimization setting.

Just download the recent master release, run on whatever device with release scheme or enable "Optimize for Speed" optimization level swift setting, and you will get different crashes based on which demo you try.

Is it possible this library has quite a few memory leaks?

I am sorry if this isn't really a very detailed issue. I happen to have a few leaks when loading a SVGLayer. If necessary I'll do more research on this.

Colored svg is rendered as black.

So I have an SVG at an URL somewhere online, and when I open it in my browser it has two colors, but when I load it with SwiftSVG it's all black. I don't want to apply fill or background colors because those are something else, but it it to have the exact colors that I see when I open the url in my browser.

Is there a setting I'm missing?

I've attached the SVG contents here https://pastebin.com/CWAdKV2Q

(Suggestion) Pattern support

I can't draw a stripped pattern defined like this:

<pattern height="8" id="diagonal-stripes" patternTransform="rotate(60)" patternUnits="userSpaceOnUse" width="8" x="0" y="0"> <rect height="8" style="stroke:none; fill:#cdd4d8;" width="3" x="0" y="0"/></pattern>

used in this way:

<path d="..." id="1870b04c-0503-4906-a9c7-b844ed2d2f10" style="fill: url(#diagonal-stripes)"/>.

Seems like fill only accepts hexadecimal colours as value.

Colouring the resulting `SVGLayer` apparently produces no effect
Colouring the resulting SVGLayer apparently produces no effect:

let image = UIView(SVGNamed: "hollow_pin") { (l: SVGLayer) -> Void in l.fillColor = UIColor.blue.cgColor l.strokeColor = l.fillColor }

The code above produces an image with a black stroke and clear fill. Am I missing something?

Support style element

Description of the Issue Browsers support the SVG style element, see: https://developer.mozilla.org/en-US/docs/Web/SVG/Element/style. Unfortunately SwiftSVG throws an error when trying to parse such files:

style is unsupported. For a complete list of supported elements, see the `allSupportedElements` variable in the `SVGParserSupportedElements` struct. Click through on the `elementName` variable name to see the SVG tag name.

Sample SVG

<svg viewBox="0 0 10 10" xmlns="http://www.w3.org/2000/svg">
  <style>
    circle {
      fill: gold;
      stroke: maroon;

resizeToFit ignores viewBox
Description of the Issue Calling resizeToFit seems to ignore the viewBox specified in the svg image and use the "actual" size of the SVG contents (while ignoring the offset, leading to rendering potentially outside of the specified rect).

Sample SVG Faulty rendering with resizeToFit: the green box is displayed outsider of the UIView, which has a grey background, see screenshot

<svg viewBox="0 0 30 30"> <rect x="10" y="10" width="10" height="10" fill="#00ff00"/> </svg>

Working as expected: When the viewBox is filled with content, scaling seems to work as expected; all three boxes are scaled to match the size of the UIView containing the SVGLayer

.

<svg viewBox="0 0 30 30"> <rect x="0" y="0" width="10" height="10" fill="#ff0000"/> <rect x="10" y="10" width="10" height="10" fill="#00ff00"/> <rect x="20" y="20" width="10" height="10" fill="#0000ff"/> </svg>
