Rami,

When you drag-drop the file, do you check the “Should this file be publicly readable?” option?
Which browser are you using?
Can you send me a Kinvey console snapshot of the “Files” for this particular file in question that would show the _acl, _public, _requiredHeaders field?

Thanks,

Pranav

• Do you see the file properly uploaded under “Files” in the Kinvey Console and its file_id?
• Is the file id that you are passing to the downloadxxx function correct? Can you verify that?
• How are you downloading the file? Can you try with the sample code provided below and let me know?

// Download File : Method 1 (using file_name of uploaded file)

let attrib = “xxxxx.jpg"

let pngQuery = KCSQuery(onField: KCSFileFileName, withExactMatchForValue: attrib as! NSObject)
       
              KCSFileStore.downloadFileByQuery(pngQuery,
                                         requestConfiguration: nil,
                                         completionBlock: { (downloadedResources: [AnyObject]!, error: NSError!) -> Void in
                                            if error == nil {                                           
                                               
                                                //extract just the Value field from the entities
                                                                                             
                                                let file = downloadedResources[0] as! KCSFile
                                               
                                                let fileURL = file.localURL
                                                let image = UIImage(contentsOfFile: fileURL.path!)
                                                //self.imgView2.image = image                                          
                                               
                                            } else {
                                                print("Got an error: ", error)
                                            }
            },
                                         progressBlock: nil
        )

// Download File : Method 2 (using file_id of uploaded file)

KCSFileStore.downloadData(“file_id_here”,
                                         requestConfiguration: nil,
                                         completionBlock: { (downloadedResources: [AnyObject]!, error: NSError!) -> Void in
                                            if error == nil {
    
                                                //extract just the Value field from the entities
                    
                                                let file = downloadedResources[0] as! KCSFile
                          let image = UIImage(data: file.data!)
                                                                                      
                                                //self.imgView2.image = image
                                                                                              
                                            } else {
                                                print("Got an error: ", error)
                                            }
            },
                                         progressBlock: nil
        )

Thanks,

Rami,

1. Can you try hardcoding the query as below with a new file that you uploaded?

let attrib = “file_name_here_along_with_extn"
let pngQuery = KCSQuery(onField: KCSFileFileName, withExactMatchForValue: attrib as! NSObject)

2. When viewing the File under "Kinvey Console=>Files”, when you click on the “Download Link” does it open the file in the browser?

I just retried the entire process once again and it just works fine at my end.

Thanks,

Pranav
