How to send 100 MB videos over URLSession

This function will send small videos only. How do I change this to send 100 MB videos? The server limits are set to 200 MB. When uploading the video I send the file path for the video to a SQL Db and the video with a unique id to the file manager. If the video is less then 5MB it returns the massage added successfully and if the video is over 5MB there's no video in the file manager. I have tried to get this but I can't work it out.

From what I understand Swift/NSURLSession will not load large amounts into memory.

Can someone show my how to convert this to work.

   func uploadVideo2 (){


        //Bool to control Post Activity Indicator.isHidden
        DispatchQueue.main.async(execute: {
        self.videoOnOff = "on"
        self.postActivityIndicatorIsHidden()
        })
    
        //Here we get the card's UUID to be used with the param
        let unquieID  =  theDictionary.value(forKey: "unquieID") as! String
    
        // param to be sent in body. This will be used in the $_request variable in the DBVideo.php
        let param = ["videoUnquieID" : unquieID] //This is the card's UUID
    
        // url path to php file
        let url = URL(string: "http://***.xxxxxxxxx.com/***/DBVideo.php")!
    
        // Adding the url to the request variable
        var request = URLRequest(url: url)
    
        // Declare POST method
        request.httpMethod = "POST"
    
        // Assign video to videoData variable
        let videoData = theDictionary.value(forKey: "theVideo") as! Data

        let boundary = "Boundary-\(UUID().uuidString)"

        request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
    

        request.httpBody = createBodyWithParamsVideo(param, //This is the card's UUID

                }
            })
            }.resume()
    }

Here is the PHP

<?php





//STEP 1. Check to see if data was passed to this php file
if (empty($_REQUEST['videoUnquieID'])) {
    $returnArray["massage"] = "Missing required information";
    return;
}


// Pass POST via htmlencryot and assign to $id
$id = htmlentities($_REQUEST['videoUnquieID']);


//STEP 2. Createing the $folder variable to hold the path where the video will be placed
$folder = "VBCVideo/";


//STEP 3. Move uploaded file
$folder = $folder . basename($_FILES["file"]["name"]);

if (move_uploaded_file($_FILES["file"]["tmp_name"], $folder)) {
    $returnArray["status"]="200";
    $returnArray["message"]="The Video file has been uploaded";
} else {
    $returnArray["status"]="300";
    $returnArray["message"]="Error while uploading the Video";
}



//STEP 4. Build connection
//Constructor to create connection
    function __construct()
    {
        require_once dirname(__FILE__) . '/Config.php';
        require_once dirname(__FILE__) . '/DbConnect.php';
        // opening db connection
        $db = new DbConnect();
        $this->connect = $db->connect();
    }



// STEP 5. Feedback array to app user
echo json_encode($returnArray);

?>

The php.ini
