ImageView to Firebase Storage in Swift

I am trying to upload an image from ImageView to Firebase storage but it won't work.

I have listed my code below: My image view is called ProfileImage

        let storageRef = Storage.storage().reference().child("myImage.png")
        if let uploadData = self.ProfileImage.image!.pngData() {
            storageRef.putFile(from: uploadData, metadata: nil) { (metadata, error) in
                if error != nil {
                    print("error")
                    completion(nil)
                } else {
                    // your uploaded photo url.
                }
            }
        }

It comes up with the error "Cannot convert value of type 'Data' to expected argument type 'URL'

I know that this question has been answered, but there is an easier way to do this. Along with import Firebase and Firebase Storage, you will also have to add FirebaseUI to your podfile and import it.

After you have done that, you could get your image to your app much simpler.

let storage = Storage.storage()
let storageRef = storage.reference()
let placeholderImage = UIImage(named: "placeholder.jpeg")
let reference = storageRef.child("myImage.png")
ProfileImage.sd_setImage(with: reference, placeholderImage: placholderImage)

(The placeholder Image would just be a transparent image that you put in your assets folder in XCode that you could reuse multiple times in your application, for whenever you needed to get a Firebase Image on your app.)

let refDatabase = Database.database().reference()
var refstorage = Storage.storage().reference()
let data = image.jpegData(compressionQuality: 1.0) // 
let metadata = StorageMetadata()
metadata.contentType = "image/jpeg"
let postkey = refDatabase.child("Post").childByAutoId().key
print(postkey)
let imagename = "PostImage/\(postkey).png"
refstorage = refstorage.child(imagename)
let timestamp = Date().timeIntervalSince1970 // you can use this to track time when it was uploaded. 
self.refstorage?.putData(data!, metadata: metadata, completion: { (meta, error) in

    if error == nil{
        if let imageData = meta?.downloadURL()?.absoluteString{
            // DO SOMETHING
        } else {
            print("Couldn't get the URL for image")
        }
    }
})

Try this code :-

let storageRef = Storage.storage().reference().child("myImage.png")
    if let uploadData = UIImagePNGRepresentation(self.profileImage.image!) {
        storageRef.put(uploadData, metadata: nil) { (metadata, error) in
            if error != nil {
                print("\(error.localizeDescription)")
            } else {                    
                // your uploaded photo url.
            }
       }

You are trying to upload Data, not a file. Replace

putFile

With

putData

And it should work fine
