[iOS] While passing the LinkedIn profile url to open the LinkedIn profile in LinkedIn app, it's opening in web

I want to open the profile of LinkedIn in LinkedIn app if app is installed otherwise in web. So, I added the code like this:

if let linkedIn = "https://www.linkedin.com/in/prakashiyerleadershipcoach" {
                            guard let linkedInAppURL =  URL(string: "linkedin:\(linkedIn)")
                            else { fatalError(Localize.validUrlExpectedMsg) }
 UIApplication.shared.open(linkedInURL, options: [:], completionHandler: nil)
                        }

Always it's redirecting to web only even if the app is installed.

I tried to resolve this issue using deep linking

let linkedIn = "https://www.linkedin.com/in/prakashiyerleadershipcoach"
            guard let linkedInAppURL =  URL(string: "linkedin://profile/prakashiyerleadershipcoach")
            else { fatalError("Invalid linkedInAppURL") }
            guard let linkedInWebURL = URL(string: (linkedIn.removingPercentEncoding)!)
            else { fatalError("Invalid linkedInWebURL") }
            if UIApplication.shared.canOpenURL(linkedInAppURL) {
                UIApplication.shared.open(linkedInAppURL)
                print("linkedinnnnn == \(linkedInAppURL)")
            } else {
                UIApplication.shared.open(linkedInWebURL, options: [:], completionHandler: nil)
                print("linkedinnnnn == \(linkedInWebURL)")
            }
}

Added LSApplicationQueriesSchemes in info.plist file

    <key>LSApplicationQueriesSchemes</key>
    <array>
        <string>linkedin</string>
    </array>

Now while clicking on link profile page is opening in app if app is installed otherwise opening in web.
But this is not the official URL schemes provided by linkedIn. I need the permanent solution for that. Can anyone help me in that. Thanks in advance!

Beginne bei den im Issue gezeigten Aufrufen von UIApplication.shared.open und canOpenURL und prüfe die dokumentierte URL-Scheme-Unterstützung der verknüpften App zusammen mit dem LSApplicationQueriesSchemes-Eintrag in Info.plist. Reproduziere die Fälle mit installierter und nicht installierter App; abgeschlossen ist die Aufgabe, wenn ein dokumentiertes, stabiles Scheme verwendet wird, sofern verfügbar, und andernfalls auf die Web-URL zurückgefallen wird.
