thanks in adance
class ViewController: UIViewController,UITableViewDataSource,UITableViewDelegate {
#IBOutlet weak var tableView: UITableView!
#IBOutlet weak var tableViewCell: UITableViewCell!
#IBOutlet weak var imageView: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "trendingCell", for: indexPath)
print(self.array[indexPath.row])
cell.textLabel?.text = (self.array[indexPath.row]["title"] as! String)
cell.detailTextLabel?.text = (self.array[indexPath.row]["username"] as! String)
Alamofire.request(imageUrl!, method: .get).response { response in
guard let image = UIImage(data:response.data!) else {
// Handle error
return
}
let imageData = UIImageJPEGRepresentation(image,1.0)
cell.myImage.image = UIImage(data : imageData!)
}
return cell
}
}

Answer 1

You are force unwrapping some values. Try to safely unwrap the values instead. You still have to figure out why the values are nil though.
dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), {
if let url = NSURL(string: self.restaurants[indexPath.row].restaurantImage), let data = NSData(contentsOfURL: url), let image = UIImage(data: data) {
dispatch_async(dispatch_get_main_queue()) { () -> Void in
cell.restaurantImage.image = image
}
}
})

This will help you figure out where the exact issue is
dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), {
guard indexPath.row < self.restaurants.count
else
{
print("Indexpath greater than restaurants count")
return
}
guard let imageUrl = NSURL(string:self.restaurants[indexPath.row].restaurantImage)
else
{
print("Image url is empty")
return
}
guard let imageData = NSData(contentsOfURL: imageUrl)
else
{
print("Cannot retreive data at url")
return
}
guard let image = UIImage(data: imageData)
else
{
print("Data doesnt contain image")
return
}
dispatch_async(dispatch_get_main_queue()) { () -> Void in
cell.restaurantImage.image = image
}
})
