How to open Safari View Controller from a Webview (swift)

I have an app that is currently using a webview and when certain links are clicked in the webview, it opens those links in Safari. I now want to implement the Safari View Controller(SVC) instead of booting it to the Safari app. I have done research and looked at examples on the SVC; however, all I see are ones that open the SVC from the click of a button. Does anyone have any suggestions for me to look at or to try?

Here is some of my code:

func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
if navigationType == UIWebViewNavigationType.LinkClicked {
let host = request.URL!.host!;
if (host != "www.example.com"){
return true
} else {
UIApplication.sharedApplication().openURL(request.URL!)
return false
}
return true

}

func showLinksClicked() {

let safariVC = SFSafariViewController(URL: NSURL(string: "www.example.com")!)
self.presentViewController(safariVC, animated: true, completion: nil)
safariVC.delegate = self }

func safariViewControllerDidFinish(controller: SFSafariViewController) {
controller.dismissViewControllerAnimated(true, completion: nil)
}

Answer

If I am understanding correctly you are loading a page on webview which has certain links now when user clicks on link you want to open those page in SVC. You can detect link click in webview using following delegate method and then open SVC from there.

EDIT

Based on edited question I can see that you are not calling showLinksClicked func , you can call this function as I have updated in following code and it should work.

 func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
    if navigationType == UIWebViewNavigationType.LinkClicked {
       self.showLinksClicked()
       return false

    }
    return true;
}


func showLinksClicked() {

    let safariVC = SFSafariViewController(URL: NSURL(string: "www.example.com")!)
    self.presentViewController(safariVC, animated: true, completion: nil)
    safariVC.delegate = self
}

func safariViewControllerDidFinish(controller: SFSafariViewController) {
    controller.dismissViewControllerAnimated(true, completion: nil)
}
