I have looked through these answer and not found anything to work. I believe its because the problem is happening for another reason for those. I am having the problem when fetching images from a database and trying to display them in on a image view.

Full code bellow:

import UIKit
import FirebaseStorage
import FirebaseDatabase
import FirebaseAuth
import Firebase

class PhaseOneViewController: UIViewController {
    
    @IBOutlet weak var p1ImageView: UIImageView!

    @IBAction func loadImages(_ sender: Any) {
        //p1ImageView.image = nil
        NKPlaceholderImage(image: UIImage(named: "placeholder"), imageView: p1ImageView, imgUrl: "\(Storage.storage().reference().child((Auth.auth().currentUser?.uid)!).child("post\(takePicViewController().finalPost + PhotoArray.sharedInstance.numberPost)").child(ImageUploadManager().imageName))") { (image) in }

    }

    func NKPlaceholderImage(image:UIImage?, imageView:UIImageView?,imgUrl:String,compate:@escaping (UIImage?) -> Void) {
        
        if image != nil && imageView != nil {
            imageView!.image = image!
        }
        
        var urlcatch = imgUrl.replacingOccurrences(of: "/", with: "#")
        let documentpath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]
        urlcatch = documentpath + "/" + "\(urlcatch)"
        
        let image = UIImage(contentsOfFile:urlcatch)
        if image != nil && imageView != nil
        {
            imageView!.image = image!
            compate(image)
            
        }else{
            
            if let url = URL(string: imgUrl){
                
                DispatchQueue.global(qos: .background).async {
                    () -> Void in
                    let imgdata = NSData(contentsOf: url)
                    DispatchQueue.main.async {
                        () -> Void in
                        imgdata?.write(toFile: urlcatch, atomically: true)
                        let image = UIImage(contentsOfFile:urlcatch)
                        compate(image)
                        if image != nil  {
                            if imageView != nil  {
                                imageView!.image = image!
                            }
                        }
                    }
                }
            }
        }
    }

}
