If you have the plist, you’ll be able to see the UIDeviceFamily (iPad = 1 | iPhone = 2 | Both iPhone and iPad, include 1 & 2 | appleTV = 3).
For Example:
UIDeviceFamily
3
Please keep in mind though that you simply cannot change that information in info.plist and save it. What we’d like for you to try is packaging your project on a Mac and see if it works or not. That’ll help us narrow down the issue.
Thanks!
