I received the fatal error
When I attempted to archive an app after installing Xcode 4 today I received the fatal error: file '/Users/Colin/Library/Developer/Xcode/DerivedData/xxx-cetiumwxozdafaelhbujogvottno/ArchiveIntermediates/xxx/BuildProductsPath/Ad Hoc-iphoneos/../../three20/Three20Network/TTURLRequest.h' modified since it was first processed.
I didn’t receive any errors while building the app for the simulator or choosing the iOS Device from Schemes List. An existing app is running the latest trunk version that worked well in Xcode 3. On the upgrade guide I have outlined the header search paths.
I’ve spent time on IRC but was unable to solve the problem. Google and Developer forums haven’t been able to help me either. Can you help me get this sorted?
Thanks for your help.
