title: Search value in strong in Swift 4
body: <p>I have this code:</p>
  
  <pre><code>let data = try Data(contentsOf: path)
  let decoder = JSONDecoder()
  let inspirationObjectArray = try decoder.decode([Inspirations].self, from: data)
  
  for inspiration in inspirationObjectArray {
      print("@@@@ \(inspiration.productCodes)")
      //showInspirationData(inspirations: product)
  }
  </code></pre>
  
  <p>the code returns the result to me:</p>
  
  <pre><code>@@@@ Optional("683500, 800264, 803821, 500513, 508500, 805108")
  </code></pre>
  
  <p>I need to check if this result is for example: 803821. How to do it?</p>
