Trying to clear document folder Swift

I use following method to add file (download) to document directory:

 static func downloadFileWithLink(linkString : String){

        // Create destination URL
        let documentsUrl:URL =  FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first as URL!
        let destinationFileUrl = documentsUrl.appendingPathComponent("downloadedFile")

        //Create URL to the source file you want to download
        let fileURL = URL(string: linkString)

        let sessionConfig = URLSessionConfiguration.default
        let session = URLSession(configuration: sessionConfig)

        let request = URLRequest(url:fileURL!)

        let task = session.downloadTask(with: request) { (tempLocalUrl, response, error) in
            if let tempLocalUrl = tempLocalUrl, error == nil {
                // Success
                if let statusCode = (response as? HTTPURLResponse)?.statusCode {
                    print("Successfully downloaded. Status code: \(statusCode)")
                }

                do {
                    try FileManager.default.copyItem(at: tempLocalUrl, to: destinationFileUrl)
                } catch (let writeError) {
                    print("Error creating a file \(destinationFileUrl) : \(writeError)")
                }

            } else {
                print("Error took place while downloading a file. Error description: %@", error?.localizedDescription);
            }
        }
        task.resume()

    }

It simply download file to document folder in sandbox. I looked for method that delete files in documents folder, and tried following:

static func deleteFiledInDocDirectory(){

        let fileManager = FileManager.default
        let tempFolderPath = NSTemporaryDirectory()
        do {
            let filePaths = try fileManager.contentsOfDirectory(atPath: tempFolderPath)
            for filePath in filePaths {
                try fileManager.removeItem(atPath: tempFolderPath + filePath)
            }
        } catch {
            print("Could not clear temp folder: \(error)")
        }
    }

However, when i inspect sandbox, downloaded file is still here. How to delete it?

In deleteFiledInDocDirectory() you're using NSTemporaryDirectory instead of the documents directory that you originally saved the file to.

Change tempFolderPath to be set using following:

guard let tempFolderPath = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first else {
    return   // documents directory not found for some reason
}

The full method:

static func deleteFiledInDocDirectory(){
    guard let tempFolderPath = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first?.absoluteString else {
        return   // documents directory not found for some reason
    }

    let fileManager = FileManager.default

    do {
        let filePaths = try fileManager.contentsOfDirectory(atPath: tempFolderPath)
        for filePath in filePaths {
            try fileManager.removeItem(atPath: tempFolderPath + filePath)
        }
    } catch {
        print("Could not clear temp folder: \(error)")
    }
}
