Swift loading images from firebase

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!))
