My app was just rejected for using the Ad support framework. Which library is responsible?

Question

This was simply an update that didn\'t change anything to do with the rejection reason. Here is the response from the resolution center:

Reasons Pro

Answer 1

In Terminal:

1. Go to the root folder of your project
2. Type: grep -r advertisingIdentifier . (the dot at the end is critical)

This will recursively check every file, and give you the name of the offending library.

(in my case, it was Flurry)
