Unexpected @ in program for @GST_IOS_PLUGINS_CATEGORIES@
I just generated a new Gstreamer framework thanks to Cerbero. I got the
`ios-framework-184.108.40.206-universal.pkg` that I installed and I linked to my
project on Xcode 10.1.
I updated my gst_ios_main.h/.m but got some unrecognized symbols by Apple.
`Unexpected @ in program for the lines
@GST_IOS_PLUGINS_CATEGORIES@ and @GST_IOS_PLUGINS_DECLARE@`
