ios - Get the value of URL Parameters

Question

I am trying to get the parameters from a URL using Swift. Let's say I have the following URL:

http://mysite3994.com?test1=blah&test2=blahblah

How can I get the values of test1 and test2?

You can use the belowCode to get the param

func getQueryStringParameter(url: String, param: String) -> String? {
  guard let url = URLComponents(string: url) else { return nil }
  return url.queryItems?.first(where: { $0.name == param })?.value
}

Call the method like let test1 = getQueryStringParameter(url, param: "test1")

Other method with extension:

extension URL {
    public var queryParameters: [String: String]? {
        guard
            let components = URLComponents(url: self, resolvingAgainstBaseURL: true),
            let queryItems = components.queryItems else { return nil }
        return queryItems.reduce(into: [String: String]()) { (result, item) in
            result[item.name] = item.value
        }
    }
}
