I recently had to figure out which version of Xcode was used to build an .ipa
file (iOS application).
Xcode adds some extra entries to the Info.plist
file. Steps:
.ipa
to a temporary locationPayload/*appname*.app/Info.plist
fileDTXcode
and DTXcodeBuild
valuesA good reference for dates/versions of Xcode is at xcodereleases.com
A complete script to do this is here
