XCode 8 VirtualBox stuck with Processing Symbol Files

Recently have an urge to learn iOS programming, downloaded XCode and try to run it in my iPhone. However life will not let you be easy. XCode seems stuck forever in 'Processing symbol files'.

Tried several solutions online, which I will outline in later part of this article, to no avail.
After some trial and error, would like to share how I solved this issue.

First please get the VirtualBox Oracle VM VirtualBox Extension Pack for your version of VirtualBox. Recommended to download from official website.

Then in your selected guest machine, please go to Setting -> USB, and check on USB 2.0 or USB 3.0

Restart the VirtualBox, and run your guest machine. Connect your iPhone to guest machine. 

(Under VirtualBox menu bar, Devices -> USB -> Select your iPhone 

Run iTunes to identify your device. 

Run XCode. You should see processing symbol files with status. 

Then select destination and run to deploy the app into your phone, Voila.

Happy coding! 

Other possible fixed online 

Use another lightning cable or USB port 

Rebooting your phone
