title: How to set UA and Headless for Selenium of Safari?
body: <h3>Ideal</h3>
  
  <p>I'd like to set User Agent and Headless for Selenium of Safari, just like ChromeOptions.
  The reason I choose Safari is that I need to capture the website which is available only for Safari.</p>
  
  <h3>What I have tried</h3>
  
  <p>I searched but found few informations.
  Then, I wrote the code below like SafariOption (mimic like ChromeOption), but it failed.</p>
  
  <pre><code>from selenium import webdriver
  import time
  
  options = webdriver.SafariOptions()
  options.add_argument('--user-agent=Mozilla/5.0 (iPhone; CPU iPhone OS 12_1_3 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/12.0 Mobile/15E148 Safari/604.1')
  
  browser = webdriver.Safari(options, executable_path = '/usr/bin/safaridriver')
  browser.get('http://google.com')
  time.sleep(10)
  browser.quit()
  </code></pre>
  
  <p>Any information is appreciated.</p>
