iOS WKWebView displays sometimes

I have a web page link that will not display via iOS WKWebView. How do I get links like this to display via WKWebView?

It appears that only 3 version of https://www.google.com and http://www.apple.com will display a Web page using http:// or https://. How do I get the other web pages to load via WKWebView? (note: all of the web sites load inside of Google Chrome and Apple Safari without using the http:// syntax.)

Below is the code from ViewDidLoad:

          @IBOutlet weak var myWebkitView: WKWebView!
          override func viewDidLoad() {
          super.viewDidLoad()


        `if let myUrl = URL(string:"https://www.ihs-us.org")`
         {

          let myURLRequest = URLRequest(url: myUrl)
          myWebkitView.load(myURLRequest)

         }

         }

      Below links works only for Apple and Google. 
     https://www.google.com will shows a Web site
     http://www.apple.com also will shows its web site
     schools.nyc.gov/SchoolPortals/08/X282 -- causes a crash
     ihs-us.org // causes a crash, and does not show a web page

All browsers append http:// to the url(if not present) and usually if a web page supports SSL, there will be a re-direction to https:// site. I developed a browser for internal use and any URL user enters, I append http:// to the URL. The simplest way would be

class func getValidURLFromString(_ urlString: String)->String{        
    if !urlString.hasPrefix("http://") && !urlString.hasPrefix("https://"){
        return "http://" + urlString
    }
    else {
        return urlString
    }
}

Edited: ViewController Code

import UIKit
import WebKit
class ViewController: UIViewController, WKUIDelegate {

@IBOutlet weak var webView: WKWebView!
override func viewDidLoad() {
    super.viewDidLoad()
    let urlString = isValidURLFormat("schools.nyc.gov/SchoolPortals/08/X282")
    let myURL = URL(string: urlString)
    let myRequest = URLRequest(url: myURL!)
    webView.load(myRequest)
}
func isValidURLFormat(_ urlString: String) -> String {
    if !urlString.hasPrefix("https://") && !urlString.hasPrefix("http://"){
        return "http://" + urlString
    }
    return urlString }

}

Plist Setting

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
        <key>NSAllowsArbitraryLoadsInWebContent</key>
        <true/>
    </dict>

Try this -

import UIKit
import WebKit

class ViewController: UIViewController{

    @IBOutlet var webView: WKWebView!

    override func viewDidLoad() {
        super.viewDidLoad()

        let urlString = "ihs-us.org"

        if urlString.hasPrefix("https://") || urlString.hasPrefix("http://"){
            let myURL = URL(string: urlString)
            let myRequest = URLRequest(url: myURL!)
            webView.load(myRequest)
        }else {
            let correctedURL = "http://\(urlString)"
            let myURL = URL(string: correctedURL)
            let myRequest = URLRequest(url: myURL!)
            webView.load(myRequest)
        }

    }

}

For schools.nyc.gov/SchoolPortals/08/X282 -

enter image description here

And for ihs-us.org -

enter image description here

You just need to do the following steps-

Open your Info.plist file of your project. Right click on it and add a row.

enter image description here

And after that just add those two lines in your (as it is) -

Info.plist`
