How do i check if url string contains a word in swift?

Question

I'm trying to forward the web view to a local file if URL doesn't contain words I want I tried many things contains and rangeofstrings didn't work for me.

  if let url = "http://facebook.com/url/url"{

        if url.contains("facebook.com") || url.contains("nocontent") || url.contains("nointernet") || url.contains("paypal.com"){
            //Doing something here
            return true
        }else{

            let htmlFile = Bundle.main.path(forResource: "nocontent", ofType: "html")
            let html = try? String(contentsOfFile: htmlFile!, encoding: String.Encoding.utf8)
            webView.loadHTMLString(html!, baseURL: nil)
        }
    }

just covert url into string & use code as var string = "hello Swift" if string.range(of:"Swift") != nil{ println("exists") } // alternative: not case sensitive if string.lowercased().range(of:"swift") != nil { println("exists") } — Gagan_iOS

try this one ..some time 'contains' does not work. Covert your url into string & check for range as mentioned in first comment. — Gagan_iOS

return URL(string: "http://facebook.com/url/url")?.absoluteString.contains("facebook.com") == true or using the host property return URL(string: "http://facebook.com/url/url")?.host?.contains("facebook.com") == true — Leo Dabus

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
}

Tip: you don't need the enclosing parenthesis.

@BoilingLime "facebook.com/url/url" will be replaced with NSURL dont worry

@O-mkar Ok, use URL instead NSURL. But URL nor NSURL implement range(of: String). You'll have to unwrap the absoluteString as follow : let urlString = URL(string: "http://facebook.com/url/url")?.absoluteString

Even "simpler" if there's only one condition: just return url.absoluteString.range(of: "facebook.com") != nil or return url.absoluteString.range(of: "facebook.com") == nil depending on the logic you need. ;)

return URL(string: "http://facebook.com/url/url")?.absoluteString.contains("facebook.com") == true

Works for me as well:

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