How to get the image url from RSS feed? - swift

Question

I'm using an MWFeed (Objective-C feed parser from GitHub ) and I'm trying to access the image from the articles in my feed . So far I've wrote this :
let item = feedItems[indexPath.row] as MWFeedItem?
cell.itemImage?.layer.cornerRadius = 25.0
cell.titleLabel.text = item?.title
if item?.content != nil {
let htmlContent = item!.content as NSString
var imageSource = ""
let rangeOfString = NSMakeRange(0, htmlContent.length)
let regex = try! NSRegularExpression(pattern: "(<img.*?src=\")(.*?)(\".*?>)", options: [])
if htmlContent.length > 0 {
let match = regex.firstMatch(in: htmlContent as String, options: [], range: rangeOfString)
if match != nil {
let imageURL = htmlContent.substring(with: match!.range(at: 2)) as NSString
if NSString(string: imageURL.lowercased).range(of: "feedburner").location == NSNotFound {
imageSource = imageURL as String
}
}
}
if imageSource != "" {
cell.itemImage?.sd_setImage(with: URL(string: imageSource), placeholderImage: UIImage(named: "Placeholder1"))
}
}
Edit : I've found out what is wrong , item.content is nil , so the code never gets called ,does anyone know why item.content = nil and how to solve it ?
This is the feed I'm using let url = NSURL(string: "https://sportingnews.com/rss")
