        if request.url?.scheme == "myapp" {
         // UIApplication.shared.open(request.url!, options: [:], //completionHandler: nil)
let myVC: MyAnotherController = MyAnotherController() 
self.present(myVC, animated: true) { }

Use this code (It will work if the URL's last character contains "#"). "#" is added because if we navigate back to the last screen, it does not open.

link(www.google.com) in web view.

func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, 
    navigationType: UIWebViewNavigationType) -> Bool {
    // request.url?.absoluteString = "www.google.com/#"
    let last = request.url?.absoluteString.last
    if last == "#" {
       //do stuff here
    }
    return true
}

From inside if block, you need to return false, and it should work. By returning false the delegate method tells that the webView should not start loading the url.

public func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {

if request.url?.scheme == "myapp" {
    // do your work here
    UIApplication.shared.open(request.url!, options: [:], completionHandler: nil)
    //Add the below line of code to the existing code
    return false
}
return true

}

You can use UIWebView delegate method optional public func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool

Example 

public func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {

    if request.url?.scheme == "myapp" {
        // do your work here
        UIApplication.shared.open(request.url, options: [:], completionHandler: nil)
    }
    return true
}

But you have to mention all the desire schemes in your app plist too..

enter image description here

Open other apps using url schemes 

if let url = URL.init(string: "myapp://") {
    if UIApplication.shared.canOpenURL(url) {
        UIApplication.shared.open(url, options: [:], completionHandler: nil)
    } else {
        print("scheme is missing in info.plist or invalid scheme")
    }
} else {
    print("invalid url")
}
