Swift loading images from firebase

Question

Does someone know why this is not working? The tableView is empty and not showing anything even though there are items in the database and storage. This worked fine before I implemented the loading of the images from storage which you will see at the bottom of this code that I have pasted in. The

food.append()

statement used to be outside the

storageRef.getData()

closure (since it didn't exist) however if I take it out now it won't be able to access

recipeImage

since it's declared within the closure. Is it not working because it's in the closure? If so how do I fix it?

let parentRef = Database.database().reference().child("Recipes")

    let storage = Storage.storage()



    parentRef.observe(.value, with: { snapshot in



        //Processes values received from server

        if ( snapshot.value is NSNull ) {



            // DATA WAS NOT FOUND

            print("– – – Data was not found – – –")



        } else {



            //Clears array so that it does not load duplicates

            food = []



            // DATA WAS FOUND

            for user_child in (snapshot.children) {



                let user_snap = user_child as! DataSnapshot

                let dict = user_snap.value as! [String: String?]



                //Defines variables for labels

                let recipeName = dict["Name"] as? String

                let recipeDescription = dict["Description"] as? String

                let downloadURL = dict["Image"] as? String



                let storageRef = storage.reference(forURL: downloadURL!)



                storageRef.getData(maxSize: 1 * 1024 * 1024) { (data, error) -> Void in



                    let recipeImage = UIImage(data: data!)



                    food.append(Element(name: recipeName!, description: recipeDescription!, image: recipeImage!))

                }

            }

            self.tableView.reloadData()

        }

    })

Move

self.tableView.reloadData()

after

food.append(Element(name: recipeName!, description: recipeDescription!, image: recipeImage!))
