        I am trying to develop an App for the School I work at. I am trying to set up several buttons that send users to a specific webpage.


        Here's my code for one of the buttons... It doesn't link to the webpage. In the simulator it sends me to the home screen, or sometimes it sends me back into xcode... (I think because it just shuts the simulator down? ) Please help.



        import UIKit

        class ViewController: UIViewController {

            @IBAction func Registrar(sender: AnyObject) {

                if let url = NSURL(string: "http://www.ajusd.org") {

                    UIApplication.shared.open(url as URL, options:[:], completionHandler:nil)




            override func viewDidLoad() {




            override func didReceiveMemoryWarning() {

          Did you try with https ?


          Otherwise, you have to declare in info.plist:

          App Transport Security Settings     // New entry

               Allow Arbitrary Loads : YES

              That should matter in this case.  When you open a URL using UIApplication, the URL opens in the target app (in this case Safari) and thus your ATS settings don’t matter.

              @sarahbrooke25, I put your code into a test app here in my office and it works just fine, both on the simulator and on a real device.  I’ve not idea what’s going on with your app.  I recommend you try reproducing this in a simple test app:

              1. Create a new app from the Single View Application template

              2. Add your method to ViewController.swift

              3. Add a button to Main.storyboard and wire it up to your method

              4. Run on the simulator

              Does that change the behaviour?
