I have just updated my OSX to Yosemite, then I ran into an error when submitting a new build to TestFlight with the TestFlight desktop app.
error: /usr/bin/codesign --force --preserve-metadata=identifier,entitlements,resource-rules --sign 2c30db522ceda29332f9f85951addff0276e0de1 --resource-rules=/tmp/sesLW20J9I/Payload/MyApp.app/ResourceRules.plist /tmp/sesLW20J9I/Payload/MyApp.app failed with error 1. Output: Warning: usage of --preserve-metadata with option "resource-rules" (deprecated in Mac OS X >= 10.10)! Warning: --resource-rules has been deprecated in Mac OS X >= 10.10! /tmp/sesLW20J9I/Payload/MyApp.app/ResourceRules.plist: cannot read resources
Anyone has got an idea?
OK, finally I find a solution to this issue. It seems that the resource rules file is not generated by default in XCode 6.1.
To generate the resource rules file as before, go to project setting, search for
Code Signing Resource Rules Path, and set its value as
$(SDKROOT)/ResourceRules.plist
After this change, rebuild your target, TestFlight desktop app will work as before.
