SFSafariViewController crash: The specified URL has an unsupported scheme

Question

My code:

if let url = NSURL(string: \"www.google.com\") {
    let safariViewController = SFSafariViewController(URL: url)
    safariViewController.view.tintColor         


        

Answer 1

I did a combination of Yuvrajsinh's & hoseokchoi's answers.

func openLinkInSafari(withURLString link: String) {

    guard var url = NSURL(string: link) else {
        print("INVALID URL")
        return
    }

    /// Test for valid scheme & append "http" if needed
    if !(["http", "https"].contains(url.scheme.lowercaseString)) {
        let appendedLink = "http://".stringByAppendingString(link)

        url = NSURL(string: appendedLink)!
    }

    let safariViewController = SFSafariViewController(URL: url)
    presentViewController(safariViewController, animated: true, completion: nil)
}
