Answer 1

Image path should be like URL format. http://dev.nsol.sg/projects/sneakers/assets/brand_images/thumb/7a53f87882409c4622a0977d5026038b.jpg.
yourJSON
message = "Success.";
newsurl = "http://dev.nsol.sg/projects/sneakers/assets/brand_images/thumb/";
success = 1;
Global Declaration:
var imgURLStringArr = [String]()
func appendURLPathFromJSON(jsonDict: NSDictionary)
{
let urlPath : String = jsonDict.value(forKey: "newsurl") as! String
let dataArr : NSArray = jsonDict.value(forKey: "data") as! NSArray
for i in 0..<dataArr.count
{
let dataDict : NSDictionary = dataArr[i] as! NSDictionary
let imageStr : String = dataDict.value(forKey: "images") as! String
let appendPath : String = urlPath + imageStr
imgURLStringArr.append(appendPath)
}
}
func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
print("willDisplaywillDisplay")
let cell = cell as! DiscoveryNewsTableViewCell
URLSession.shared.dataTask(with: NSURL(string: self.imgURLStringArr[indexPath.row])! as URL, completionHandler: { (data, response, error) -> Void in
if error != nil {
print(error ?? "No Error")
return
}
DispatchQueue.main.async(execute: { () -> Void in
let image = UIImage(data: data!)
cell.thumbImg.image = image
})
}).resume()
}
