The file “IMG_0001.JPG” couldn’t be opened because you don’t have permission to view it - swift

Question

I'm using JSQMessagesViewController to send photo messages in my chats and I face this problem when I'm trying to upload image from gallery. Here is my code:
override func didPressAccessoryButton(_ sender: UIButton) {
let picker = UIImagePickerController()
picker.delegate = self
if (UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.photoLibrary)) {
picker.sourceType = UIImagePickerControllerSourceType.photoLibrary
}
present(picker, animated: true, completion:nil)
}
func imagePickerController(_ picker: UIImagePickerController,
didFinishPickingMediaWithInfo info: [String : Any]) {
picker.dismiss(animated: true, completion:nil)
// 1
if let photoReferenceUrl = info[UIImagePickerControllerReferenceURL] as? URL {
// Handle picking a Photo from the Po8hoto Library
// 2
let assets = PHAsset.fetchAssets(withALAssetURLs: [photoReferenceUrl], options: nil)
let asset = assets.firstObject
// 3
if let key = sendPhotoMessage() {
// 4
asset?.requestContentEditingInput(with: nil, completionHandler: { (contentEditingInput, info) in
let imageFileURL = contentEditingInput?.fullSizeImageURL
// 5
let path = "\(FIRAuth.auth()?.currentUser?.uid)/\(Int(Date.timeIntervalSinceReferenceDate * 1000))/\(photoReferenceUrl.lastPathComponent)"
// 6
self.storageRef.child(path).putFile(imageFileURL!, metadata: nil) { (metadata, error) in
if let error = error {
print("Error uploading photo: \(error.localizedDescription)")
return
}
// 7
self.setImageURL(self.storageRef.child((metadata?.path)!).description, forPhotoMessageWithKey: key)
}
})
}
} else {
// Handle picking a Photo from the Camera - TODO
}
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
picker.dismiss(animated: true, completion:nil)
}
I`ve read a lot about it in google ( The file “xxx.mp4” couldn’t be opened because you don’t have permission to view it ) , but unfortunately, there is no solution for it. Please help me to understand how could I fix this warning?
Whole warning message:
Body file is unreachable:
/var/mobile/Media/PhotoData/Sync/100SYNCD/IMG_0001.JPG Error
Domain=NSCocoaErrorDomain Code=257 "The file “IMG_0001.JPG” couldn’t
be opened because you don’t have permission to view it."
UserInfo={NSURL=file:///var/mobile/Media/PhotoData/Sync/100SYNCD/IMG_0001.JPG, NSFilePath=/var/mobile/Media/PhotoData/Sync/100SYNCD/IMG_0001.JPG,
NSUnderlyingError=0x17464d4a0 {Error Domain=NSPOSIXErrorDomain Code=1
"Operation not permitted"}} Error uploading photo: An unknown error

P.S. this works good in emulator, I'm getting this warning only at real device.

I've rewrite imagePickerController method, now it works perfect
func imagePickerController(_ picker: UIImagePickerController,
didFinishPickingMediaWithInfo info: [String : Any]) {
picker.dismiss(animated: true, completion:nil)
let stRef = FIRStorage.storage().reference()
let metaData = FIRStorageMetadata()
metaData.contentType = "image/jpeg"
if let photo = info[UIImagePickerControllerOriginalImage] as? UIImage {
var data = NSData()
data = UIImageJPEGRepresentation(photo, 0.25)! as NSData
if let key = sendPhotoMessage() {
let path = "\(FIRAuth.auth()?.currentUser?.uid)/\(Int(Date.timeIntervalSinceReferenceDate * 1000)))"
stRef.child(path).put(data as Data, metadata: metaData){ (metaData,error) in
if error != nil {
return
}
else {
let downloadURL = metaData!.downloadURL()!.absoluteString
self.setImageURL(downloadURL, forPhotoMessageWithKey: key)
}
}
}
} else {
// Handle picking a Photo from the Camera - TODO
}
}
