Using the Firebase repository putFile () method causes the file "fileName" cannot be opened.

Question

Here are two ways I tried to upload a file:

1.

getURLOfPhoto(assetURL: imagesDictionary[String(whichProfileImage)]! , completionHandler: { (responseURL) in          
                                    FIRStorage.storage().reference().putFile(responseURL as! URL)
                            })

2.

  let assets = PHAsset.fetchAssets(withALAssetURLs: [imagesDictionary[String(whichProfileImage)] as! URL], options: nil)
            let asset = assets.firstObject
            asset?.requestContentEditingInput(with: nil, completionHandler: { (contentEditingInput, info) in
                let imageFile = contentEditingInput?.fullSizeImageURL?

                FIRStorage.storage().reference().child("test").putFile(imageFile!, metadata: nil) { (metadata, error) in
                        if let error = error {                   
                            return
                        }   
                }
            })

I get this error:

 Body file is unreachable: /var/mobile/Media/DCIM/100APPLE/picture.JPG        
    Error Domain=NSCocoaErrorDomain Code=257 "The file "picture.JPG" couldn’t be opened because you don’t have permission to view it."     
        UserInfo={NSURL=file:///var/mobile/Media/DCIM/100APPLE/picture.JPG, NSFilePath=/var/mobile/Media/DCIM/100APPLE/picture.JPG,     
    NSUnderlyingError=0x15da49a0 {Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted"}}

It seems that the URL was successfully restored, and the error only occurs when the method is called putFile().

Does anyone know how to fix this error or another way to upload a file (not a Data object) to Firebase storage?

Thanks in advance

Firebase Storage URL- , PHAsset, (, , ) - , iPhone. , , Firebase Storage API, , URL- putFile().

, imagePickerController():

do {
   let documentsURL = FileManager.default().urlsForDirectory(.documentDirectory,
                                                                          inDomains: .userDomainMask)[0]
   let fileURL = try documentsURL.appendingPathComponent("fileName.jpg")

   let image = info[UIImagePickerControllerOriginalImage]

   try UIImageJPEGRepresentation(image as! UIImage,1.0)?.write(to: fileURL, options: [])

                    FIRStorage.storage().reference().child("exampleLocation")
                        .putFile(fileURL, metadata: nil) { (metadata, error) in
    if let error = error {
                                print("Error uploading: \(error.description)")
