@Bentoon

I just ran into this and solved it, so I hope I can help.

Apparently, something has changed relatively recently because I didn’t used to have to do this.
You need to, in XCode, add the “Security” and “SystemConfiguration” frameworks to the XCode project.

Check out this stackoverflow answer for adding frameworks. Don’t worry, they are built in to XCode apparently.
