I'm struggling with how to get and save the image url of the pictures to database. I also need to know how to store images with unique names all the time so old images don't get deleted by new ones.

  let storage = Storage.storage().reference()
        guard  let imageData = ecoImage.jpegData(compressionQuality: 0.75) else {
            return
        }

        let metaData = StorageMetadata()
        metaData.contentType = "image/jpg"

            storage.child("pins/\(uid)").putData(imageData, metadata: metaData) { (StorageMetadata, error) in
            guard StorageMetadata != nil else{
                print("oops an error occured while data uploading")
                return
            }
                 print("Image sent")
            }

doc.setData(["uid": uid, "pinLocation": Pin, "time": timeData]) { (error) in
            if error != nil {
                print(error?.localizedDescription)
                return
            } else {
                print("Pin saved")
            }
        }

I not sure about Firebase but this video might help #1 Grocery App - Setting Up Firebase with Xcode 12 and then there #2 as well.

@BlackNoirImpost3 - Did you come up with a working resolution for this in the end?

Hi, i have interpolated my data set. I would like to check which method will be best suited for my data. Reference data for cross validation is missing. Is any other method exit with which i can check which interpolation technique will be best suited for my data set?
