How to open a URL in Swift?

openURL has been deprecated in Swift 3.

Can anyone provide some examples of how the replacement openURL:options:completionHandler: works when trying to open a url?

All you need is:

guard let url = URL(string: "http://www.google.com") else {
  return //be safe
}

if #available(iOS 10.0, *) {
    UIApplication.shared.open(url, options: [:], completionHandler: nil)
} else {
    UIApplication.shared.openURL(url)
}
