I am trying to upload a video to firebase storage that is saved in FileManager as a URL looking like this file:///Users/admin/Library/Developer/CoreSimulator/Devices/D9BA697D-2ACA-4C4F-BE64-9004016A8500/data/Containers/Data/Application/1133A56A-B92F-4A8A-B9D9-0A8180607B93/Documents/videorecording.mp4. I tried uploading it like this:
private func persistVideoToStorage(id: String, video: URL) {
let ref = FirebaseManager.shared.storage.reference(withPath: id)
ref.putData(video, metadata: nil) { metadata, err in
if let err = err {
print(err)
return
}
ref.downloadURL { url, err in
if let err = err {
print(err)
return
}
guard let url = url else { return }
}
}
}
But I need to upload the type of Data and cannot convert URL to Data.
Try something like this:
do {
let videoData = try Data(contentsOf: video)
//....
ref.putData(videoData, metadata: nil)
//....
} catch {
print("-- Error: \(error)")
}

I wanted to know what is the best way to fetch images which are uploaded by the user on my app. Currently, the images are all being saved in storage. I assume this is not the correct way as it has nothing to do with userId? Perhaps, I need to save user media in real time database in order to fetch their images? If someone could help me, that will be much appreciated.
Thank you.
guard let image = imageView.image, let data = image.jpegData(compressionQuality: 1.0)
else {
print("something went wrong")
return
}
let imageName = UUID().uuidString
let imageReference = Storage.storage().reference().child(MyKeys.imagesFolder).child(imageName)
imageReference.putData(data, metadata: nil) { (metadata, err) in
if let err = err {
print ("Error")
return
}
imageReference.downloadURL(completion: { (url, err) in
if let err = err {
print ("Error")
return
}
guard let url = url else {
print ("Error")
return
}
let dataReference = Firestore.firestore().collection(MyKeys.imagesCollection).document()
let documentUid = dataReference.documentID
let urlString = url.absoluteString
let data = [
MyKeys.uid:documentUid,
MyKeys.imageUrl: urlString,
MyKeys.imageTitle: self.imageTitle.text!,
] as [String : Any]
dataReference.setData(data) { (err) in
if let err = err {
print ("Error")
return
}
}
})
}
}
A pretty common pattern is to store the user ID in the image's path in Firebase Storage. For example,
let imageName = //...
guard let uidString = Auth.auth().currentUser?.uid else {
return
}
let imageRefPath = "\(uidString)/\(imageName)"
I have an image that is uploaded to the Firebase Storage but I can not get the downloadURL of this to save it in my database.
I already read a lot of posts on StackOverflow but there was nothing working out for me. The image is loaded into the storage but the error says that it is not existing.
let image = self.selectedImage
let imageData = UIImageJPEGRepresentation(image, 0.1)
let storageRef = Storage.storage().reference().child(uid)
storageRef.putData(imageData, metadata: nil) // i know that i can use a completion here but i left it for now
storageRef.downloadURL { url, error in
if let error = error {
print(error)
} else {
// do sth. else
}
}
These are the errors that I get:
FIRStorageErrorDomain Code=-13010 "Object W002MjRvi0d8JfVwImUJhH0ph2O2 does not exist."UserInfo={object=W002MjRvi0d8JfVwImUJhH0ph2O2,
ResponseBody={
"error": {
"code": 404,
"message": "Not Found. Could not get object"
}
}
ResponseErrorDomain=com.google.HTTPStatus, ResponseErrorCode=404}
Please check Storage Rules
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if request.auth!=null;
}
}
}
In Your ViewController
import Firebase
import FirebaseAuth
import ImageIO
var imgData: NSData = NSData(data: UIImageJPEGRepresentation((self.img_Photo?.image)!, 0.5)!)
self.uploadProfileImageToFirebase(data: imgData)
func uploadProfileImageToFirebase(data:NSData){
guard let userID = Auth.auth().currentUser?.uid else {
return
}
let storageRef = Storage.storage().reference().child(“Images”).child(userID)
if data != nil {
storageRef.putData(data as Data, metadata: nil, completion: { (metadata, error) in
if(error != nil){
print(error)
return
}
// Fetch the download URL
storageRef.downloadURL { url, error in
if let error = error {
// Handle any errors
if(error != nil){
print(error)
return
}
} else {
// Get the download URL for 'images/stars.jpg'
let urlStr:String = (url?.absoluteString) ?? ""
}
}
})
}
}
When using an image picker to grab the image selected and place in firebase storage I want to be able to download the URL and take place of the profile image inside the app. Unfortunately, when the process reaches the URLSession in the script nothing happens. There is not an error display nor does it dispatchQueue. The app will not crash but just skip over everything. Any ideas or suggestions to a code fix?
if let profileImageUploadedData = self.profileImage.image, let uploadData = profileImage.image?.jpegData(compressionQuality: 0.1)
{
storageRef.putData(uploadData, metadata: nil, completion: { (metadata, error) in
if error != nil
{
print("Downdloading putData Error: \(error!.localizedDescription)")
return
}
storageRef.downloadURL(completion: { (url, error) in
if error != nil
{
print("DownloadURL ERROR \(error!.localizedDescription)")
return
}
if let profileImageUrl = url?.absoluteString
{
print("Profile image uploading...")
let values = ["profileImageUrl": profileImageUrl]
let url = URL(fileURLWithPath: profileImageUrl)
URLSession.shared.dataTask(with: url) { (data, response, error) in // ERROR OCCURING NEED TO FIX
if error != nil
{
print("* URL SESSIONS ERROR: \(error!)")
return
}
DispatchQueue.main.async
{
print("Trying to register profile")
self.registerUserIntoDatabaseWithUID(uid: uid, values: values as [String : AnyObject])
self.profileImage.image = UIImage(data: data!)
print("Dispatch: \(data!)")
}
print("Profile image successfull uploaded to storage")
}
}
})
}).resume()
print("** Profile Image Data Uploaded:\(profileImageUploadedData)")
}
}
func registerUserIntoDatabaseWithUID(uid: String, values: [String: AnyObject])
{
print("Registering to database")
let dataReference = Database.database().reference(fromURL: "URL String")
let usersReference = dataReference.child("users").child(uid)
usersReference.updateChildValues(values, withCompletionBlock: { (err, reference) in
if err != nil
{
print(err!)
return
}
// self.profileImage.image = values["profileImageUrl"] as? UIImage
// self.fetchProfileImage()
self.dismiss(animated: true, completion: nil)
print("Saved user sussccessfully in database")
})
}
}
This is a big question that is actually asking for a number of different answers so let's just focus on one;
How to authenticate a user, get a url stored in Firebase Database that
references an image stored in Firebase Storage, then download that
image.
Here we go
First - authenticate a user
Auth.auth().signIn(withEmail: user, password: pw, completion: { (auth, error) in
if let x = error {
//handle an auth error
} else {
if let user = auth?.user {
let uid = user.uid
self.loadUrlFromFirebaseDatabase(withUid: uid)
}
}
})
now the user is authenticated, get the image location url from Firebase Database
func loadUrlFromFirebaseDatabase(withUid: String) {
let thisUserRef = self.ref.child("users").child(withUid)
let urlRef = thisUserRef.child("url")
urlRef.observeSingleEvent(of: .value, with: { snapshot in
if let url = snapshot.value as? String {
self.loadImageUsingUrl(url: url)
} else {
print("no image for user")
}
})
}
Now that we have the location of the image in Firebase Storage, get it
func loadImageUsingUrl(url: String) {
let storage = Storage.storage()
let imageRef = storage.reference(forURL: url)
imageRef.getData(maxSize: 1 * 1024 * 1024) { data, error in
if let error = error {
print("error downloading \(error)")
} else {
if let image = UIImage(data: data!) {
//do something with the image
} else {
print("no image")
}
}
}
}
I'm having trouble getting my image to download in from user input. Whenever I try to upload the image I get the error screen. I'm working in Xcode 9 with swift 4.0.
if let imgData = UIImageJPEGRepresentation(img, 0.2){
let imgUid = NSUUID().uuidString
let metadata = StorageMetadata()
metadata.contentType = "image/jpeg"
let storageItem = Storage.storage().reference().child(imgUid)
storageItem.putData(imgData, metadata: metadata) { (metadata, error) in
if error != nil {
print("Couldn't Upload Image")
} else {
print("Uploaded")
storageItem.downloadURL(completion: { (url, error) in
if error != nil {
print(error!)
return
}
if url != nil {
self.setUser(img: url!.absoluteString)
}
}
)
}
}
}
I'm trying to create a function that uploads images to Firebase Storage and returns the download url for their path so I can use it other parts of the app.
This is what the function looks like:
func uploadImage(to reference:StorageReference, image:UIImage) -> URL? {
let imageData = UIImageJPEGRepresentation(image, 0.2)
let metadata = StorageMetadata()
metadata.contentType = "image/jpeg"
var downloadURL = metadata.downloadURL()
reference.putData(imageData!, metadata: metadata) { (metadata, error) in
if error != nil {
print("Couldnt upload due to \(String(describing: error))")
}
downloadURL = metadata?.downloadURL()
}
return downloadURL!
}
I can't seem to get the result that I want as downloadUrl always returns nil. What am I doing wrong?
The problem here is that your function is returning before the upload is complete. In other words your function needs to return a callback, rather than a plain URL. Something like -
func uploadImage(to reference:StorageReference, image:UIImage, completion: #escaping (URL?) -> Void) {
let imageData = UIImageJPEGRepresentation(image, 0.2)
let metadata = StorageMetadata()
metadata.contentType = "image/jpeg"
var downloadURL = metadata.downloadURL()
reference.putData(imageData!, metadata: metadata) { (metadata, error) in
if error != nil {
print("Couldnt upload due to \(String(describing: error))")
completion(nil)
} else {
if let downloadUrl = metadata?.downloadURL() {
completion(downloadUrl)
} else {
completion(nil)
}
}
}
}
