ERROR : ViewController.swift:29:23: 'init(contentsOfURL:options:)' has been renamed to 'init(contentsOf:options:)' — Osama Altmeme, Jun 30 '17 at 13:37
Don't use `NSArray`. Use a Swift array. Don't use `NSURL`, use `URL`. Don't use `NSData`, use `Data`. — rmaddy, Jun 30 '17 at 13:56

func dataJsonFromURL(url:String) -> [String: Any]? {
    if let realUrl = URL(string: url) {
        do {
            let data = try Data(contentsOf: realUrl)
            if let json = try JSONSerialization.jsonObject(with: data, options:[]) as? [String: Any] {
                return json
            }
        } catch {
            //error
        }
