Hi, I'm joining very late but I'm struggling to understand something.
I know that this needs to be after what it used to be "Embed App Extensions" which now I think is called "Embed Foundation Extensions"
But when I generate my (desired) only extension, this is only shown at Build Phases of the default target but not in the other ones. I'm trying to understand if that does not matter? If i build my app with target #2, and the script is between Build phases of target #1, still works? Thank you :)
