Swift-5 Very Simple Way

//MARK:- In my case i have an array so i am checking the object in this
    for object in yourArray {
        if object is NSNull {
            print("Hey, it's null!")

        }else if object is String {
            print("Hey, it's String!")

        }else if object is Int {
            print("Hey, it's Int!")

        }else if object is yourChoice {
            print("Hey, it's yourChoice!")

        }
        else {
            print("It's not null, not String, not yourChoice it's \(object)")
        }
    }
