build fails in AppCode, works in other IDE, no real clue as to what is going on

Yves,
do you open xcodeproj, or xcworkspace files?
Please attach the Build Log (the button on the 'Messages' wool window's toolbar).

xcodeproj.  

This got me looking in the AppCode GUI, found the console, and in there i found a clue (still does not explain why this works in Xcode) ... hmmm :

/Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -workspace /Users/yvesleborg/devel/MaxPowerProject/MaxPower/Battles/Battles.xcodeproj/project.xcworkspace -scheme "Battles Lite Dev" -configuration Debug -sdk iphoneos5.0 SYMROOT=/Users/yvesleborg/Library/Caches/appCode10/DerivedData/Battles-a544448a/Build/Products OBJROOT=/Users/yvesleborg/Library/Caches/appCode10/DerivedData/Battles-a544448a/Build/Intermediates ARCHS=armv7 ONLY_ACTIVE_ARCH=NO TEST_AFTER_BUILD=NO build

Yves,

I've created a bug report for missing error message: http://youtrack.jetbrains.com/issue/OC-4628.
As for why it builds in Xcode - I cannot say. Please let us know if you find out.

ok, i created the .entitlements on the dark side (dont know how or whether it is feasable with AppCode 1.5.6), and that fixed the build issue. Strange, Xcode should also have failed on that dependancy. Thanks Anton.
