Loading an Image file from Firebase Storage using SDWebImage - swift

Question

I am trying to load an image from my Firebase Storage to be displayed on my app view.
I have 2 classes mainly
Main "ClassView" that includes a tableView.
A custom tableViewCell - "ClassCell" (This class includes an imageView where I want to display the picture from firestore. - imageView is called classImage.
Below is the tableView Data Source Extension.
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
tableView.register(UINib(nibName: K.tableCellNibName, bundle: nil), forCellReuseIdentifier: K.tableCellIdentifier)
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let storageRef = storage.reference()
let reference = storageRef.child(K.FStore.classImagesPath)
let placeholderImage = UIImage(named: "placeholder.png")
let imageView: UIImageView = self.imageView
let cell = tableView.dequeueReusableCell(withIdentifier: K.tableCellIdentifier, for: indexPath) as! ClassCell
//below is where I try to set the my image but it is not changing anything
cell.classImage?.sd_setImage(with: reference, placeholderImage: placeholderImage)
//This I tried to make sure that I am can access the image right and it worked just fine
// cell.classImage?.backgroundColor = .black
return cell
}
The Image is not displayed using the sd_setImage method. Any help would be highly appreciated if I have any error in my code or missing a declaration anywhere.
Below is what I am getting when I run the simulator. Instead of the image displayed in these black boxes, they are empty. Also, the imageView.image is returning nil so most probably the sd_setImage is not placing the image right.

Answer 1

self.imgSidebarMenuImage.sd_imageIndicator = SDWebImageActivityIndicator.whiteLarge
self.imgSidebarMenuImage.sd_setImage(with: URL(string: (person["image"] as! String)), placeholderImage: UIImage(named: "logo"))
try this
#1
let storage = Storage.storage().reference(withPath: “YOUR_PATH”)
storage.downloadURL { (url, error) in
if error != nil {
print((error?.localizedDescription)!)
return
}
print(“Download success”)
//url = your will get an image URL
self.someImageURL = url!
}
#2
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// cell identifier methods
var item = itemData[indexPath.row]
let referenceImage: StorageReference = storageRef.child("YOUR_PATH")
let url = URL(string: referenceImage!)!
cell.itemImage?.sd_setImage(with: url, placeholderImage: #imageLiteral(resourceName: "placeholder"))
}
}
return cell
}
