Code:

let fileManager = FileManager.default
let documentsFolder = try! fileManager.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false)
let folderURL = documentsFolder.appendingPathComponent(folderName)
let folderExists = (try? folderURL.checkResourceIsReachable()) ?? false
do {
if !folderExists {
try! fileManager.createDirectory(at: folderURL, withIntermediateDirectories: false)
}
let destinationFileUrl = folderURL.appendingPathComponent("test23.pdf")
// let hello = Data("hello".utf8)
// try hello.write(to: fileURL)
let urlString = ""
let url = URL(string: urlString)
let fileName = String((url!.lastPathComponent)) as NSString
// Create destination URL
/* let documentsUrl:URL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first as URL!
let destinationFileUrl = documentsUrl.appendingPathComponent("\(fileName)")*/
//Create URL to the source file you want to download
let fileURL = URL(string: urlString)
let sessionConfig = URLSessionConfiguration.default

let request = URLRequest(url:fileURL!)
let task = session.downloadTask(with: request) { (tempLocalUrl, response, error) in

if let statusCode = (response as? HTTPURLResponse)?.statusCode {
print("Successfully downloaded. Status code: \(statusCode)")
}

try FileManager.default.copyItem(at: tempLocalUrl, to: destinationFileUrl)
do {
//Show UIActivityViewController to save the downloaded file
let contents = try FileManager.default.contentsOfDirectory(at: documentsFolder, includingPropertiesForKeys: nil, options: .skipsHiddenFiles)
for indexx in 0..<contents.count {
if contents[indexx].lastPathComponent == destinationFileUrl.lastPathComponent {

I assume you need to change from create:false to create:true
Change from
let documentsFolder = try! fileManager.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false)
To
let documentsFolder = try! fileManager.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: true)
