title: NSUbiquitousKeyValueStore: Ambiguous use of 'set(_:forKey:)'
body: <p>I'm using Xcode 8.3 beta 2 (8W120l) and can't get this line of code to work:</p>
  
  <pre><code>NSUbiquitousKeyValueStore.default().set(["one", "two"], forKey: "key")
  </code></pre>
  
  <p>Here is the error I get:</p>
  
  <pre><code>Ambiguous use of 'set(_:forKey:)'
  </code></pre>
  
  <p>This piece of code compiles perfectly on Xcode 8.2.1 (8C1002).</p>
  
  <p>I can't find any info on how to get this code compile.</p>
