In my project I am using Kanna it is more easy to use in Swift projects.

Link to GitHub repo.

In Kanna you can fetch info you need in this way:

let html = "<a href=q/?s=wig20>WIG20</a></td><td><span id=aq_wig20_c2>2305.67</span></td><td nowrap><span id=aq_wig20_m1><font id=c1>+0.38%</font></span></td><td></td><td nowrap><span id=aq_wig20_d1>9:23</span></td></tr><tr>"

if let doc = Kanna.HTML(html: html, encoding: String.Encoding.utf8) {
   let bodyNode   = doc.body

   if let inputNodes = bodyNode?.xpath("//a | //span") {
      for node in inputNodes {
          print(node.content)
      }
   }
 }

Response:

Optional("WIG20")
Optional("2305.67")
Optional("+0.38%")
Optional("9:23")

All data is in html elements that are <a> and <span>.
