Swift 2.2 enumerateObjectsUsingBlock - stop
<p>Prior to Swift 2.2 I could stop an enumeration by making the stop parameter mutable with var and then setting it appropriately<code>stop = UnsafeMutablePointer&lt;ObjCBool&gt;.alloc(NSNumber(bool: true).integerValue)</code></p>

<p>Now in 2.2 making a parameter mutable is deprecated so how do I stop an enumeration? </p>
