title: ARC-Type conversion causes compiler error
body: <p>i am having a problem in type conversion in ARC environment.if anyone would be kind enough to address it as well:</p>
  
  <p>when i used this line of code:</p>
  
  <p><code>OSStatus status = SecItemCopyMatching((CFDictionaryRef) CFBridgingRetain(attributeQuery), (CFTypeRef*)&amp;attributeResult);</code></p>
  
  <p>then i am having error :</p>
  
  <p><code>cast of an indirect pointer to an objective C pointer to 'CFTypeRef *' is disallowed with ARC.</code></p>
  
  <p>Please suggest me any way to ressolve this.. 
  Thanks in advance..</p>
