RestKit - Lipo Error: can't open input file in Xcode5

Question

I have an iOS application that i need to upgrade on iOS7. I am using RestKit version 0.10.2. While archiving i get following error.

/Applications/Xcode 2.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: can't open input file: /Users/khawarshahzad/Library/Developer/Xcode/DerivedData/MyAPP-fcvmsuowvnqkdseskmuetssnxoww/Build/Intermediates/ArchiveIntermediates/MyAPP/IntermediateBuildFilesPath/MyAPP.build/Release-iphoneos/MyAPP.build/Objects-normal/armv7s/MyAPP (No such file or directory)

Previously i had fixed this error for iOS6 by following instructions on https://github.com/RestKit/RestKit/issues/930

But now its not working for iOS7. Here is screenshot for current RestKit.xcodeproj Architectures settings.

Any suggestion is appreciated.

Huh! finally found the solution. If you are not using any specific feature of arm64 architecture, then just kick it off. Go to project -> target (your project name) -> build settings and change architectures to standard architectures (armv7, armv7s), and valid architectures to armv7, armv7s. Set Build Active Architecture Only to Yes

Repeat same for RestKit.xcodeproj

Clean your project and Archive. Best of Luck :)
