Youtube Video Id from URL - Swift3

Question

Basically I have a Youtube URL as string, I want to extract the video Id from that URL. I found some code in objective c that is as below:

NSError *error = NULL;         


        

Answer 1

I have a different way of doing this using URLComponents. You then just select the 'v' parameter from the url, if it exists.

func getYoutubeId(youtubeUrl: String) -> String? {
    return URLComponents(string: youtubeUrl)?.queryItems?.first(where: { $0.name == "v" })?.value
}

And then pass in a Youtube url like this:

print (getYoutubeId(youtubeUrl: "https://www.youtube.com/watch?v=Y7ojcTR78qE&spfreload=9"))
