Answer 1

This should do the job :

if let url = URL(string: "http://facebook.com/url/url") {

    if url.absoluteString.range(of: "facebook.com") != nil {

        return true
    }

    return false
}

Answer 2

Works for me as well:

if url.absoluteString.contains("facebook.com") {
    // do something here
}

Answer 3

This works for me

guard url.path.contains("facebook.com")  else { return nil }
 //do what you want
