Background Download Task is not working

[shamith-kumar-sclera]

The Download is not Working in the background mode even if i entitled all the necessary permission for the application it only works when the app is connected to xcode due to xcode keep the session alive but if try after removing the connection from the xcode the app not able to keep the download after 45 sec what may be the reason

my code

  var request = URLRequest(url: url)
        request.httpMethod = "GET"
        
        let bearerToken = SyncManager.accessToken
        request.setValue("Bearer \(bearerToken)", forHTTPHeaderField: "Authorization")
        
        let uniqueIdentifier = "\(self.vdmsId)_\(UUID().uuidString)"
        
        backgroundTaskID = UIApplication.shared.beginBackgroundTask { [weak self] in
            if let taskID = self?.backgroundTaskID {
                UIApplication.shared.endBackgroundTask(taskID)
                self?.backgroundTaskID = .invalid
            }
        }
        
        
        let CursessionConfig = URLSessionConfiguration.background(withIdentifier: uniqueIdentifier)
        
        
        CursessionConfig.isDiscretionary = false
        CursessionConfig.sessionSendsLaunchEvents = true
        CursessionConfig.shouldUseExtendedBackgroundIdleMode = true
           
           // Set timeout intervals
        CursessionConfig.timeoutIntervalForResource = 24 * 60 * 60 // 24 hours
        CursessionConfig.timeoutIntervalForRequest = 60 * 60 // 1 hour
        
        let Cursession = URLSession(configuration: CursessionConfig, delegate: self, delegateQueue: nil)
        
        
        self.CurInstanceSession  = Cursession
        
        
        self.session = Cursession
        if  SyncManager.activeSessions == nil {
            SyncManager.activeSessions = [URLSession]()
        }
        
        SyncManager.activeSessions?.append(Cursession)
        
        self.downloadCompletionHandler = completion
        
        let CurdownloadTask = Cursession.downloadTask(with: request)
        
        CurdownloadTask.resume()

is there any solutions and i have entitled all the neccessary permisssions like background fetch, process and i also tries with the UIApplication.shared.beginBackgroundTask but after 45 sec it gets terminated all of the suden what may be the issue

@shamith-kumar-sclera Can you please try using the Transfer Utility as described here in this documentation https://docs.amplify.aws/gen1/swift/sdk/storage/transfer-utility/

@harsh62 thank you for the replay, but i am not using the the AWS s3 bucket mine is simple file download from the REST server running remotely
since this is similar to the issue you faced once can you provide me the insights on this issue (not working in the background after 45 sec in the background)

@shamith-kumar-sclera Unfortunately I can only help you with AWS SDK related questions.
