title: DISPATCH_QUEUE_T in Swift 3
body: <p>I'm programming my first Swift 3 but I came across the following error</p>
  
  <p><strong>dispatch_queue_t is unavailable in swift.</strong> </p>
  
  <pre><code>var queue: dispatch_queue_t?
  
  var debugPrint = false
  
  public init() {
      let uuid = NSUUID().uuidString
      let queueLabel = "tomlogger-queue-" + uuid
      queue = dispatch_queue_create(queueLabel, DISPATCH_QUEUE_SERIAL)
  
  }
  </code></pre>
  
  <p>Does anyone know how I solve this error, </p>
  
  <p>Thomas</p>
