What need to provided in redirect url, as a developer do need to have server to create for that ?

This library doesn't require a working URI endpoint in order to get the authorization code after the user authorizes your app. The authorization code is captured by the WKWebView instance presenting the authentication dialog. Still, a valid URL is required by LinkedIn, so you can add whatever URL you want. https://example.com will do the job.
