How to access <g> attributes of a SVG resource using PocketSVG?

Question

I have been trying to use PocketSVG to parse SVG resources. Using PocketSVG, I can easily parse all the paths of the SVG and the path attributes too. Following https://stackoverflow.com/a/40683062/3939807 answer, here is the sample code I have tried.

guard let url = Bundle.main.url(forResource: shape, withExtension: "svg") else { return nil }
let paths = SVGBezierPath.pathsFromSVG(at: URL)

for path in paths {
   let shapeLayer = CAShapeLayer()
   layer.path = path.CGPath

   var strokeWidth = CGFloat(4.0)
   var strokeColor = UIColor.black.cgColor
   var fillColor = UIColor.white.cgColor

   // Inspect the SVG Path Attributes
   print("path.svgAttributes = \(path.svgAttributes)")

   if let strokeValue = path.svgAttributes["stroke"] {
      strokeColor = strokeValue as! CGColor
   }

   if let fillColorVal = path.svgAttributes["fill"] {
      fillColor = fillColorVal as! CGColor
   }

   // Set its display properties
   shapeLayer.lineWidth = strokeWidth
   shapeLayer.strokeColor = strokeColor
   shapeLayer.fillColor = fillColor

   // Add it to the layer hierarchy
   self.view.layer.addSublayer(shapeLayer)
}

But I need to access some of the group attributes to get the actual result of the SVG. A sample SVG resource source code:

<svg xmlns="http://www.w3.org/2000/svg" width="590.092" height="570.076" viewBox="0 0 590.092 570.076">
<g id="Group_84" data-name="Group 84" transform="translate(-5576.16 -1736.816)">
<path id="Path_120" data-name="Path 120" d="M235.181,359.121l145.342,87.723-38.57-165.332L470.362,170.271l-169.1-14.346L235.181,0,169.1,155.925,0,170.271,128.409,281.512,89.839,446.844Z" transform="translate(5607.22 1833.337) rotate(-8)" fill="none" stroke="#f1c502" stroke-linecap="round" stroke-linejoin="round" stroke-width="55"/>
<path id="Path_121" data-name="Path 121" d="M5790.9,1956.979l45.432-158.481,92.976,145.8" fill="none"/>
<path id="Path_122" data-name="Path 122" d="M5931.647,1944.786l163.137-7.768-108.757,130.214" fill="none"/>
<path id="Path_123" data-name="Path 123" d="M5985.659,2070.376l64,157.588-156.848-68.436" fill="none"/>
<path id="Path_124" data-name="Path 124" d="M5886.89,2160.083l-130.584,109.5,18.126-169.241" fill="none"/>
<path id="Path_125" data-name="Path 125" d="M5772.028,2095.9s-148.709-93.591-146.49-93.221,166.1-44.761,166.1-44.761" fill="none"/> </g> </svg>

There is an attribute named transform="translate(-5576.16 -1736.816)" under <g> tag. My question is how can I get this attribute and apply it using PocketSVG. Any kind of help will be appreciated.

Thanks in advance.

The solution is very straight forward. Each path contains UIBezierPath and it's all atributes in svgAttributes which is of type Dictionary [String: Any]

if let url = Bundle.main.url(forResource: "shape", withExtension: "svg") {
    let paths = SVGBezierPath.pathsFromSVG(at: url)
        
        for path in paths {
            let svgAttributes = path.svgAttributes
            let transform = svgAttributes["transform"]
        }
    }
