title: String Array to String conversion Swift
body: <p>I have a string array stored in nsuserdefaults under <code>someKey</code> key.</p>
  
  <p>I'm building the <code>Alamofire</code> query:</p>
  
  <pre><code>var params = [
          "long": lon,
          "lat": lat,
          "startDate": DateCalc.convertValueToDate(defaults.floatForKey("startDate"))
      ] as [String: AnyObject]
  
  Alamofire.request(.GET, "\(serverURL)/tests", parameters: (params))
          .validate()
          .responseJSON { response in
  </code></pre>
  
  <p>Now, based on some conditions, I would like to append to my <code>params</code> array the previously set String array.</p>
  
  <p>I tried doing it like this:</p>
  
  <pre><code>params["someKey"] = defaults.objectForKey("someKey")
  </code></pre>
  
  <p>but then the input params look as follows:</p>
  
  <pre><code>params: ["long": 19.09421499999999, "someKey": &lt;__NSCFArray 0x7f8322713990&gt;(
  </code></pre>
  
  <p>one,
  two,
  three
  )
  , "lat": 51.90671500000001,"startDate": 2011-09-28T00:00:00.000Z]</p>
  
  <p>how should I change it so that I can pass the array of strings instead, e.g.:</p>
  
  <pre><code>params: ["long": 19.09421499999999, "someKey": "one, two three", "lat": 51.90671500000001,"startDate": 2011-09-28T00:00:00.000Z]
  </code></pre>
