Using Xcode 10.1, Swift 4.2 and Firebase ##

I can't see datas in my realtime database after uploading the datas to firebase with the following code:

static func createUser(username: String, email: String, password: String, imageData: Data, onSuccess: @escaping () -> Void, onError: @escaping (_ error: String?) -> Void) 

 Auth.auth().createUser(withEmail: email, password: password) (data, error) in
 if let err = error 
 onError(err.localizedDescription)
 return
 
 // User erfolgreich erstellt
 guard let uid = data?.user.uid else return 
 self.uploadUserData(uid: uid, username: username, email: email, imageData: imageData, onSuccess: onSuccess)
 


static func uploadUserData(uid: String, username: String, email: String, imageData: Data, onSuccess: @escaping () -> Void) 


 let storageRef = Storage.storage().reference().child("profile_image").child(uid)

 storageRef.putData(imageData, metadata: nil) (metadata, error) in
 if error != nil 
 return
 
 

 storageRef.downloadURL(completion: (url, error) in
 if error != nil 
 print(error!.localizedDescription)
 return
 

 let profilImageURL = url?.absoluteString


 let ref = Database.database().reference().child("users").child(uid)
 ref.setValue(["username" : username, "email" : email, "profileImageURL": profilImageURL ?? "Kein Bild vorhanden"])

 )
 onSuccess()

The settings in firebase:

Should work the right way. I already looked at the firebase documentation and didn't find more informations.

Does the image get uploaded to Cloud Storage? If it does but the download URL isn't written to the database, my guess is it's because the data isn't uploaded before you generate the download URL. Since the upload function is asynchronous, the downloadURLfunction should be called from the closure.

static func uploadUserData(uid: String, username: String, email: String, imageData: Data, onSuccess: @escaping () -> Void) {

 let storageRef = Storage.storage().reference().child("profile_image").child(uid)

 storageRef.putData(imageData, metadata: nil) (metadata, error) in
 if error != nil 
 return
 
 storageRef.downloadURL(completion: (url, error) in
 if error != nil 
 print(error!.localizedDescription)
 return
 
 onSuccess()
