let session_config = URLSessionConfiguration.background(withIdentifier: "cxxczuifgdgd")
let session = URLSession(configuration: session_config)
let task=session.downloadTask(with: request) { (url, response, error) in
print("anusha")
}
task.resume()
created a url session for background downloads as above...but app is getting crashed with error...
libc++abi.dylib: terminating with uncaught exception of type NSException

Completion handler blocks not supported in background sessions?
Correct. It’s impossible for a background session to support completion handler blocks because:
Such blocks can capture arbitrary state from your process
Your process can be terminated while the task is running and then relaunched to handle completion

It literally uses this code, which crashes with the above error when actually used.
Can we get some retraction here?
