Hi, I am trying to upload an image to FileStore but keep getting the following error:

"fatal error: unexpectedly found nil while unwrapping an Optional value"

When I started to debug, it seems like the code is failing inside a Kinvey function as shown below:

 if let _ = file.fileId {

               var request = URLRequest(url: file.uploadURL!)

It is failing at the var request line. The Kinvey documents do not tell me to specify an upload URL, so I am not sure if this is supposed to be assigned automatically or not.

Note: The upload function was working, before I updated to the latest Kinvey SDK.

Any help with this will be appreciated.

Thanks,

Divey

Hi Pranav,

Thanks for your response. 

1. Yes I am using iOS SDK 3.3.8

2. Yes, the example provided in the link is the exact example I am using, please see my code below.

@objc func uploadUserImage(image: UIImage, imageId: String, notiName: String, name: String){

        let uploadFileStore = FileStore.getInstance()

        let file = File()

        file.publicAccessible = true

        file.fileId = imageId

        file.fileName = name

        uploadFileStore.upload(file, image: image){file, error in

            if error != nil{

                //Failed

                NotificationCenter.default.post(name: Notification.Name(rawValue: notiName), object: nil, userInfo: ["profilePicConf": "notSaved"])

            }

            else{

                //Success

                NotificationCenter.default.post(name: Notification.Name(rawValue: notiName), object: nil, userInfo: ["profilePicConf": "Saved"])

            }

        }

    }

3. The error is in the Kinvey file called FileStore.swift, which I cannot edit. I have attached a photo of the error file with the error showing. This error occurs when I call my uploadUserImage method shown above.

Hi Pranav,

I have replaced my code with the code from your previous comment. The code is now as below. The error is still the same. Please help.

   @objc func uploadUserImage(imagePath: NSString, imageId: String, notiName: String, name: String){

        let uploadFileStore = FileStore.getInstance()

        let file = File()

        file.publicAccessible = true

        file.fileId = imageId

        file.fileName = name

        var image = UIImage(contentsOfFile: imagePath as String)

        let path = imagePath as String

        uploadFileStore.upload(file, path: path){file, error in

            if error != nil{

            }

            else{

                print("Success")

            }

        } 

Thanks.

Your code does not work for me. One thing I did notice is your file path says Kinvey No Pod. I downloaded Kinvey using Cocoapods, would that cause any issues?

Thanks.

Hi Billy,

Thanks for your quick help with this, I really appreciate it. I am now able to upload images, but unable to mark the acl as global. There has been a ticket raised on the forum 4 days ago "Swift set ACL globalRead = true for files", so I am surprised that this issue has not been fixed in the recent release.

At this stage the upload function is useless to me as I need the ability for public readable photos.

Please help me with this.

Thanks.
