Open WKWebView Links in Safari

I'm creating an app that uses WKWebView. Whenever a user clicks on a link in that webview, I want the link to open up in safari instead of inside the webview. I'm really new at coding, so please make it as easy as possible. I just need the code I need to add. Here's the code bellow:

import UIKit
import WebKit
class FirstViewController: UIViewController {
   
    @IBOutlet var containerView: UIView! = nil
   
    var webView: WKWebView?
   
    override func loadView() {
        super.loadView()
       
        self.webView = WKWebView()
        self.view = self.webView!
       
    }
   
    override func viewDidLoad() {
        super.viewDidLoad()
       
        var url = NSURL(string:"http://www.example.com/")
        var req = NSURLRequest(url:url as! URL)
        self.webView!.load(req as URLRequest)
    }
   
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }
   
}

I'm using Xcode 8 and Swift 3
