Everything is ready to work now, but there must be some steps are kept in mind that,
-> while testing links did not work directly in browsers or safari. So keep a link in Notes or any other app to click.
-> If by mistake once you open that link into browser, the iPhone will store that
in preference and next time it will always open it in the browser. Even if you uninstall the app and reinstall that it will not work. To make it work again just long pressed on a link and once open that link with your application. So now it will be working fine again.
