import SafariServices
import UIKit

extension UIApplication {
  
  var firstKeyWindow: UIWindow? {
    return UIApplication.shared.connectedScenes
      .compactMap { $0 as? UIWindowScene }
      .filter { $0.activationState == .foregroundActive }
      .first?.keyWindow
  }
  
  func showSafariView(url: URL?) {
    guard let url else { return }
    
    let vc = SFSafariViewController(url: url)
    firstKeyWindow?.rootViewController?.present(vc, animated: true)
  }
  
}

Use it in your views like so:

// This button will present an SFSafariController as a navigation controller when tapped. 
Button {
  UIApplication.shared.showSafariView(url: item.destinationURL)
} label: {
  ItemView(item: item)
} 

Using this method avoids weird issues with double navigation bars, etc.
