iOS swift extracting permalink from deeplink URL

I am implementing Firebase dynamic links in my iOS project. It is working fine and it is opening my iOS Home screen properly. But now I would like to extract values from url and open appropriate screen based on url.

for example: https://www.dd.com/forums/hot-deals-online/topics/smart-tv-carniva

in this url I would like to get 'hot-deals-online' and 'smart-tv-carniva' permalink which I will pass to view controller to open that screen on the app

can someone suggest me best approach for this.

Shortest is to access path of URLComponents object:

let url = "https://www.dd.com/forums/hot-deals-online/topics/smart-tv-carniva"

if let comps = URLComponents(string: url) {
    var elements = comps.path.split(separator: "/").map(String.init)
    // ["forums", "hot-deals-online", "topics", "smart-tv-carniva"]


    // To build an url back, example:
    var url = URL(string: comps.host!)!
    url.appendPathComponent(elements[0])
    url.appendPathComponent(elements[1])
    // Result: www.dd.com/forums/hot-deals-online
}

P.S. calling .map(String.init) makes in-place conversion from array of substrings to normal String array.
