对成员'putData'错误的引用不明确

Question

Making a simple app that involves uploading pictures but I can't figure out how to get by this error. Yes I'm super new to swift and firebase.

 guard let image = self.plusPhotoButton.imageView?.image else { return }
        guard let uploadData = image.jpegData(compressionQuality: 0.3) else { return }

        let filename = NSUUID().uuidString

        let storageRef = Storage.storage().reference().child("profile_images").child(filename)
        storageRef.putData(uploadData, metadata: nil, completion: { (metadata, err) in

            if let err = err {
                print("Failed to upload profile image:", err)
                return
            }
        },
        storageRef.downloadURL(completion: { (downloadURL, err) in
            if let err = err {
                print("Failed to fetch downloadURL:", err)
                return

            }
            guard let profileImageUrl = downloadURL?.absoluteString else { return }

            print("Successfully uploaded profile image:", profileImageUrl)
        })


    )}
    }

Got this error:

Ambiguous reference to member 'putData'
Expressions are not allowed at the top level
Use of unresolved identifier 'uploadData'
Expected ')' in expression list

There is one error in brackets Closing.

guard let image = self.plusPhotoButton.imageView?.image else { return }
        guard let uploadData = image.jpegData(compressionQuality: 0.3) else { return }

        let filename = NSUUID().uuidString

        let storageRef = Storage.storage().reference().child("profile_images").child(filename)
        storageRef.putData(uploadData, metadata: nil, completion: { (metadata, err) in

            if let err = err {
                print("Failed to upload profile image:", err)
                return
            }
        },
        storageRef.downloadURL(completion: { (downloadURL, err) in
            if let err = err {
                print("Failed to fetch downloadURL:", err)
                return

            }
            guard let profileImageUrl = downloadURL?.absoluteString else { return }

            print("Successfully uploaded profile image:", profileImageUrl)
        })


    )}  //Replace With }) 
}
