SFSafariController loads URL fine in simulator but leaves a blank screen on device

Question

So I'm using SFSafariController to load up an URL downloaded from cloudkit, like so.

    if let yelpurl = detail.value(forKey: "Yelp") as? String
    {

        let url = URL(string:  (yelpurl))
        let safari = SFSafariViewController(url: url!, entersReaderIfAvailable: false)
        safari.delegate = self as? SFSafariViewControllerDelegate
        self.present(safari, animated: true, completion: {

        })
    } else {
    }

}

The code itself is fine - no errors, pulls up the yelp page URL and loads it up in an SFSafariController in simulator, but on my device, I am left with a white blank screen. What is causing this disparity and how can I correct this on device?

To add, the plist still stands without any modification.

Edit 1: I created a new project to purely test the below mentioned code to possibly discover a new error. This is what I found - and wondering how to solve.

Update: I updated to 10.3.3 and deleted my browsing history.

Answer 1

Just created a sample project and it works on both simulator and iPhone 6S iOS 10.3.2, code:

import UIKit
import SafariServices

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let deadlineTime = DispatchTime.now() + .seconds(1)
        DispatchQueue.main.asyncAfter(deadline: deadlineTime) {
            self.showLinksClicked()
        }

    }

    func showLinksClicked() {

        let yelpurl = "https://google.com"
        let url = URL(string:  (yelpurl))
        let safari = SFSafariViewController(url: url!, entersReaderIfAvailable: false)
        safari.delegate = self as? SFSafariViewControllerDelegate
        self.present(safari, animated: true, completion: {
        })
    }
}

So looks like something is wrong with your URL or with way you call the method to present safari. Put your code to a separate method and be sure that you pass right URL.
