Url scheme for compose email with Gmail and Spark

mail.swift

import UIKit

class ViewController: UIViewController {
    
    @IBAction func gmail(_ sender: Any) {
        let compose = "googlegmail:///co?subject=Subject&body=some text&to=test@example.com"
            .addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!
        let url = URL(string: compose)!
        if UIApplication.shared.canOpenURL(url) {
            UIApplication.shared.open(url)
        }
    }
    
    @IBAction func spark(_ sender: Any) {
        let compose = "readdle-spark://compose?subject=Subject&body=some text&recipient=test@example.com"
            .addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!
        let url = URL(string: compose)!
        if UIApplication.shared.canOpenURL(url) {
            UIApplication.shared.open(url)
        }
    }
}

Необходимо добавить запрашиваемые схемы (googlegmail, readdle-spark) в Info.plist по ключу LSApplicationQueriesSchemes

is there a way to attach a document into the e-mail?
