App rejected, but I don’t use UDID
In My case it was ibGoogleAnalytics_debug.a library. To find which library is using uniqueidentifier method, go to your project folder and type in: $ find . | grep -v .svn | grep “\.a” | grep -v “\.app” | xargs grep uniqueIdentifier I got this: Binary file ./My_Project/libGoogleAnalytics_debug.a matches
