Firebase storage upload works in Simulator but not on iPhone

Question

Any reason why Xcode would complain to me about permissions in regards to uploading an image to Firebase Storage but when I run the same app in the Simulator, it works fine?

Permissions Error:

Body file is unreachable: /var/mobile/Media/DCIM/100APPLE/IMG_0974.JPG Error Domain=NSCocoaErrorDomain Code=257 "The file “IMG_0974.JPG” couldn’t be opened because you don’t have permission to view it." UserInfo={NSURL=file:///var/mobile/Media/DCIM/100APPLE/IMG_0974.JPG, NSFilePath=/var/mobile/Media/DCIM/100APPLE/IMG_0974.JPG, NSUnderlyingError=0x14805d680 {Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted"}}

Answer 1

I'm having the same problem right now. Uploading works fine in the Simulator, but on a device it gives me the permission error. My workaround has been to upload the image as data rather than with the URL to the file:

let imageData = UIImageJPEGRepresentation(image, 1.0)
let uploadTask = storageReference.child(remoteFilePath).putData(imageData, metadata: metadata, completion: { (metadata, error) in
    // Your code here
}

Uploading works fine in the Simulator, but on a device it gives me the permission error. Upload the image as data rather than with the URL to the file:

Declare first

    fileprivate lazy var storageRef: StorageReference = Storage.storage().reference(forURL: "gs://yourAPP.appspot.com/")

then

     let path : String = "\(String(describing: Auth.auth().currentUser?.uid))/\(Int(Date.timeIntervalSinceReferenceDate * 1000))/\(photoReference)"

                // 6

                let imageData = UIImageJPEGRepresentation(photoReference, 0.1)
                let uploadTask = self.storageRef.child(path).putData(imageData!, metadata: nil, completion: { (metadata, error) in
                    // Your code here
                    if let error = error {
                        print("Error uploading photo: \(error.localizedDescription)")
                        return
                    }

                    // 7
                    self.setImageURL(self.storageRef.child((metadata?.path)!).description, forPhotoMessageWithKey: key)
                })
