title: How to encrypt using AES GCM on iOS?
body: <p>I need to encrypt/decrypt some data using AES encryption on GCM mode, but apparently this can't be done with the CommonCrypto API. This has been asked previously <a href="https://stackoverflow.com/questions/23681571/is-it-possible-to-use-aes128-with-gcm-mode-on-ios">here</a>, but the accepted answer is not what I'm looking for, since I need to use this specific algorithm. </p>
  
  <p>Any ideas? Should I use OpenSSL? Because I've heard that there are some bugs when using it in iOS.</p>
  
  <p>I'm looking for an answer in Swift, but Objective-C would be fine as well.</p>
