title: check if any property in an object is nil - Swift 3
body: <p>Im using Swift 3</p>
  
  <p>Wondering whether any method is available to check if all the properties in an object has value / nil</p>
  
  <p>Eg: </p>
  
  <pre><code>class Vehicle {
  var name : String?
  var model: String?
  var VIN: String?
  }
  
  let objCar = Vehicle()
  objCar.name = "Volvo"
  
  if objCar.{anyProperty} ! = nil {
  //Go to other screen
  }
  </code></pre>
  
  <p>Im in search of the {anyProperty} method where it returns true only if I have values for all properties of objCar. In our case, objCar has no model and VIN and so {anyProperty} is false and will come out of if loop</p>
  
  <p>Pls advice</p>
