I am implementing a "Tabbet App" and I need a "Tab" to open a URL in Safari (new window not in the same viewcontroller)

Currently for example in the viewcontroller of Tab4 (Tab4ViewControllerView.swif) I have added the following code:

 guard let url = URL(string: "https://google.com") else 
 return //be safe
 

 if #available(iOS 10.0, *) 
 UIApplication.shared.open(url, options: [:], completionHandler: nil)
 else 

 UIApplication.shared.openURL(url)
 

It works but when I return from Safari to the application, Tab4 is selected and since it does not contain anything it looks white.

I need to click on Tab4 to open Safari but it should not be selected (you must keep selecting the previous tab.)

In the example of the image: I am currently in Tab1 and pressing Tab4 should open Safari but keeping selected Tab1

Add to your UITabBarController extension with UITabBarControllerDelegate, also set to your Tab 4 restoration Id

in TabBarViewContoller add:

import UIKit

class TabBarViewController: UITabBarController 

 override func viewDidLoad() 
 super.viewDidLoad()
 delegate = self
 // Do any additional setup after loading the view.
 


extension TabBarViewController: UITabBarControllerDelegate 
 func tabBarController(_ tabBarController: UITabBarController, shouldSelect viewController: UIViewController) -> Bool 
 if viewController.restorationIdentifier == "safariTabViewController" 
 if let url = URL(string: "your_url"), UIApplication.shared.canOpenURL(url) 
 UIApplication.shared.openURL(url)
 
 return false
 
 return true
 

when you returning false in delegate - you make sure that tab will not be switched

You should embed a webView in tab4, using WKWebView or UIWebView. This way you won't have to leave your application.

Something like,

let webView = WKWebView()



override func loadView() 
 self.view = webView



if let url = URL(string: "https://www.apple.com") 
 let request = URLRequest(url: url)
 webView.load(request)
