title: Access all passwords in the iCloud keychain
body: <p>I'm currently able to retrieve every password in the user keychain thanks to the <code>SecKeychain</code> API, with the <code>SecItemCopyMatching</code> method.
  But if I specify the <code>kSecAttrSynchronizable</code> attribute to true, I only get the password I added myself previously with the <code>SecItemAdd</code> method.</p>
  
  <p>Is there a way to also get the passwords stored by the system or more particularly by Safari?</p>
  
  <p>Thanks for your answers.</p>
