For Swift 5.6 and Xcode 13.4

I opened name "Images" folder in Firebase and uploaded my image which name "Corleone" in jpg format.

Firstly I fetch image data then assigned to imageView. Lastly, i downloaded image URL. You can use two method differently.

You can copy all what i wrote and past your project inside of viewDidload or buttonAction.

 let storage = Storage.storage().reference().child("Images/Corleone.jpg")
    
    storage.getData(maxSize: 1 * 1024 * 1024) { data, error in
        if error != nil {
            print(error?.localizedDescription ?? "errror")
        }else{
            let image = UIImage(data: data!)
            self.imageView.image = image
            
            storage.downloadURL { url, error in
                if error != nil {
                    print(error?.localizedDescription ?? "error")
                }else {
                    print(url ?? "url") //https://firebasestorage.googleapis.com/v0/b/epeycompare.appspot.com/o/Images%2FCorleone.jpg?alt=media&token=04c6369d-8036-4aef-8052-bac21c89eeda

                }
            }
        }
    }

Install the pod firebaseUI.

import FirebaseUI

fetch the reference from the storage and set the reference to the imageview directly using SDwebimage as shown below.

let ref2 = Storage.storage().reference(forURL: "gs://hungry-aaf15.appspot.com/Listings/Food/-MV04bNvewyGPHMYUkK9/MainImage") 

cell.img.sd_setImage(with: ref2)

Specify path and it's extension, then Use:

let path = "Listings/Food/-M3g8pZDGmApicUAQtOi/MainImage.jpg"
let reference = Storage.storage().reference(withPath: path) 

reference.getData(maxSize: (1 * 1024 * 1024)) { (data, error) in
        if let err = error {
           print(err)
      } else {
        if let image  = data {
             let myImage: UIImage! = UIImage(data: image)

             // Use Image
        }
     }
}
