title: How to share keychain data between iOS applications
body: <p>I am describing a problem for which it took me quite some time to learn the answer.</p>
  
  <p>The "<a href="http://developer.apple.com/library/ios/#samplecode/GenericKeychain/Introduction/Intro.html" rel="noreferrer" title="GenericKeychain">GenericKeychain</a>" example is a good start at providing a wrapper for sharing keychain data between applications when using the accessGroup in the init.</p>
  
  <p>However, implementing this in my app yielded an obscure error code (which took forever to locate) -25243, which means: No access control.</p>
  
  <p>I ran Apple's example app (GenericKeychain) on my iPad only to get the same error. Huh?</p>
  
  <p>Does Apple's documentation fail to deliver on what is necessary to accomplish this?</p>
