Swift 3 - How to download Profile Image from FireBase Storage - swift

Question

I need help on retrieving Image from firebase storage, i learned how to save it but cant download it to current user profile.
here is my code so far:
FIRAuth.auth()?.createUserWithEmail(email!, password: password!, completion: { (authData, error) in
if error == nil {
if (password == "" || name == "" || email == "") {
self.showAlert("error", message: " Please Fill In The Blank")
}
if (password != confirm_password) {
self.showAlert("ERROR", message: "Password Don't Match")
}
}
else {
self.showAlert("ERROR", message: "Please Try Again")
}
let filePath = "\(FIRAuth.auth()!.currentUser!.uid)/\("userPhoto")"
var data = NSData()
let metaData = FIRStorageMetadata()
//let imageName = NSUUID().UUIDString
let storageRef = FIRStorage.storage().referenceForURL("gs://storageURL")
storageRef.child(filePath).putData(data, metadata: metaData){(metaData,error) in
if let error = error {
print(error.localizedDescription)
return
}
if let ProfileImageUrl = metaData?.downloadURL()?.absoluteString {
let values : [String : AnyObject] = ["name": name!, "email": email!, "profileImageUrl": ProfileImageUrl]
self.userPost(values)
}
}
})
}
//save data in Database
func userPost(values: [String: AnyObject]) {
let ref = FIRDatabase.database().referenceFromURL("https://databaseURL.firebaseio.com/")
ref.child("users").childByAutoId().setValue(values)
}
so i got that so far but cant figure out how to download it to user profile.
here is my code for user ProfileVC:
#IBOutlet weak var ProfileImg: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.retriveData()
ProfileImg.image = UIImage(named: "ic_account_circle.png")
imagePicker.delegate = self
}
func DownloadProfilePhoto() {
let storageRef = FIRStorage.storage().referenceForURL("gs://StorageURL.com")
let filePath = "\(FIRAuth.auth()!.currentUser!.uid)/\("userPhoto")"
}
Please Help.....

Answer 1

You need to download the image data, and then create an image. You should try this:
let storage = FIRStorage.storage()
var reference: FIRStorageReference!
reference = self.storage.referenceForURL("gs://appname.appspot.com/filePath")
reference.downloadURLWithCompletion { (url, error) in
let data = NSData(contentsOfURL: url!)
let image = UIImage(data: data!)
ProfileImg.image = image
}
You should check the Firebase documentation https://firebase.google.com/docs/storage/ios/download-files

For people looking for swift 4
let storage = Storage.storage()
var reference: StorageReference!
reference = storage.reference(forURL: "gs://appname.appspot.com/filePath")
reference.downloadURL { (url, error) in
let data = NSData(contentsOf: url!)
let image = UIImage(data: data! as Data)
cell.imgOutlet.image = image
}
