title: Determine if the device is ARM64
body: <p>I'm trying to make a tweak for iOS 7 so that when a device is ARM64 it runs one version and when it is not it runs another (since float is for 32 bit and double is for 64 (If you have a solution for that let me know.)</p>
  
  <p>So it would be like this</p>
  
  <pre><code>if ARM64 {
      \\run double code
  }
  else {
      \\run float code
  }
  </code></pre>
