Xcodebuild does not work on the write helper files phase

Question

I am doing a clean archive:

xcodebuild -workspace MyApp.xcworkspace \ -scheme MyScheme \ -archivePath /Library/......./outputfolder/MyApp.xcarchive \ clean archive 

I get this error in about 50% of cases.

 The following build commands failed: Write auxiliary files 

It has been reported twice on Apple Developer Forums (but not yet on StackOverflow, as far as I know).

Has anyone found a reason or workaround?

Answer 1

This issue has been fixed with the release of Xcode 5.1.1. the release notes contained 2 obscure references to 2 bug fixes in the 'Build System', which I suppose fixes the problem.

Updates should occur automatically. If you don’t go to the application store and install the command line tools update and the latest Xcode.

Answer 2

I saw this error with the assembly that used cocoapods.

Updating to the latest (0.31.1 from the moment of writing) fixed the problem for me.

This can be done with: (sudo) gem install cocoapods
