I am trying to use swiftyjson and I am getting an Error:

Call can throw, but it is marked with \'try\' and the error is not handled.

You should wrap it into a do-catch block. In your case:

do {
    let session =  URLSession.shared.dataTask(with: url) {
        (data, response, error) in
            guard let data = data else {
            print ("data was nil?")
            return
        }

        let json = JSON(data: data)
        print(json)
    }
} catch let error as NSError {
    // error
}
