I tried to resign my ipa file with new provisioning profile on Mac Os 10.10 with iResign app but I got this warning: \"Warning: --resource-rules has been deprecated in Mac O
I just opened my existing iOS app in Xcode 7 GM (from Xcode 6.4) and saw this deprecation warning.
It's interesting that answers and comments are saying to update the 'Code Signing Resource Rules Path' and they also reference Mac apps.
In my case, the project had this key and value already set by default (I never set it). The warning is about resource rules being deprecated too.
For me, deleting the value of the 'Code Signing Resource Rules Path' removed the warning. I have not submitted a new build this way so I may have to come back and update this answer.
Just thought it was interesting that my answer is opposite what everyone else was seeing.
