Upload Image from the gallery into Firebase with Swift 4.2 - ios

Question

I've got a problem regarding Firebase and the upload of pictures..
I've been tried to follow the Firebase doc but I'm not sur to do the right things ...
In my application I want to send in firebase the value of 2 textfields and 1 segmented control plus one picture which is coming from the iphone's gallery.
well my save button :
#IBAction func saveBtnWasPressed(_ sender: Any) {
//Informations from the segmented control
if isMe == false {// Si SE
acftType = "SE"
}else if isMe == true {//Si ME
acftType = "ME"
}
let ref = Database.database().reference()
let userID = Auth.auth().currentUser?.uid
let usersPlanes : NSDictionary = [ "Registration" : self.acftRegTxtField.text!,
"model": self.acftModelTxtField.text!,
"Type" : self.acftType]
if isMe == false {// Si SE
ref.child("Planes").child(userID!).child("SE").childByAutoId().setValue(usersPlanes)
}else if isMe == true {//Si ME
ref.child("Planes").child(userID!).child("ME").childByAutoId().setValue(usersPlanes)
}else{
print("Error: Impossible to find the type of aircraft...")
}
let Dpalert = UIAlertController(title: nil, message: "Your informations as been upload", preferredStyle: .alert)
Dpalert.addAction(UIAlertAction(title: "Roger", style: .cancel, handler: nil))
self.present(Dpalert, animated: true)
}
And my function to allow user to select an image from his gallery is :
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
let userID = Auth.auth().currentUser?.uid
self.dismiss(animated: true, completion: nil)
if let selectedImage = info[UIImagePickerController.InfoKey.editedImage] as? UIImage {
self.planImageView.image = selectedImage
var data = Data()
data = selectedImage.jpegData(compressionQuality: 0.75)!
}else{
print("Error : Impossible to deal with this image...")
}
let imageRef = Storage.storage().reference().child("Images").child(userID!).child(randomString(20));
let uploadPict = imageRef.putData(data, metadata: nil){ (metadata, error) in
guard let metadata = metadata else {
return
}
let size = metadata.size
imageRef.downloadURL { (url, error) in
guard let downloadURL = url else {
return
}
}
}
But nothing appears in firebase when the picture is load in the app and How can I add it in the same folder as my first 3 information send with the save button ?
I'm totally lost with all this information. How can I solve my problem ?
Thanks very much for your help !

In this function
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
let userID = Auth.auth().currentUser?.uid
self.dismiss(animated: true, completion: nil)
if let selectedImage = info[UIImagePickerController.InfoKey.editedImage] as? UIImage {
self.planImageView.image = selectedImage
var data = Data()
data = selectedImage.jpegData(compressionQuality: 0.75)!
}else{
print("Error : Impossible to deal with this image...")
}
let imageRef = Storage.storage().reference().child("Images").child(userID!).child(randomString(20));
let uploadPict = imageRef.putData(data, metadata: nil){ (metadata, error) in
guard let metadata = metadata else {
return
}
let size = metadata.size
imageRef.downloadURL { (url, error) in
guard let downloadURL = url else {
return
}
}
}
Try to put an output when your putData fail
let uploadPict = imageRef.putData(data, metadata: nil){ (metadata, error) in
guard let metadata = metadata else {
print("Error with upload \(String(describing: error?.localizedDescription))")
return
}
let size = metadata.size
imageRef.downloadURL { (url, error) in
guard let downloadURL = url else {
print("Error with download URL: \(String(describing: error?.localizedDescription))")
return
}
}
Maybe it will help you to recognize the error; tell me what you got in the error
