Downloading/Displaying URL path Swift 3 - php

Question

I am attempting to download/display a JPEG image from a URL path saved in my MYSQL DB. I can retrieve the path in full and search for it on a browser which verifying it exists within the DB. However, I once I have the URL path, I can not download it properly or display it as a UIImage in a cell on in my TableView Controller.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "activity", for: indexPath) as! CustomCell
let post = activities[indexPath.row]
//print(post["path"])
//let image = images[indexPath.row]
let imaged = post["path"] as! String
//print(imaged)
let image = URL(string: imaged)! //download url
print(image)
let username = post["username"] as? String
let text = post["text"] as? String
let session = URLSession(configuration: .default)
let downloadPicTask = session.dataTask(with: image) {
(data, response, error) in
if let e = error {
print("Error downloading image: \(e)")
} else {
if (response as? HTTPURLResponse) != nil {
if let imageData = data {
let pic = UIImage(data: imageData)
print(pic)
cell.activityImage.image = pic
self.images.append(pic!)
} else{
print("couldn't get image: image is nil")
}
} else {
print("Couldn't get response code")
}
}
}
cell.titleLabel.text = text
cell.usernameLabel.text = username
downloadPicTask.resume()
return cell
}
