I have just updated my Xcode to version 7.2. Now I try to build a framework from command line using xcodebuild but have this error

Everything worked well in XCode 7.1. so there must be something changed in XCode 7.2. Anyone has a clue?
Edit:
this is my build commmand
This works
xcodebuild clean build -workspace XYZ.xcworkspace -scheme ABC -configuration Debug -sdk iphoneos
This doesn't work:
xcodebuild clean build -workspace XYZ.xcworkspace -scheme ABC -configuration Debug -sdk iphonesimulator
One possible workaround would be to supply a destination by adding the following:
-destination 'platform=iOS Simulator,name=iPhone 6'
In your case this would like this:
xcodebuild clean build -workspace XYZ.xcworkspace \
-scheme ABC -configuration Debug \
-sdk iphonesimulator \
-destination 'platform=iOS Simulator,name=iPhone 6'
Try to specify the destination, i.e, xcodebuild -workspace 'App.xcworkspace' -scheme 'App Scheme' -destination 'id=[THE_SIMULATOR_ID_YOU_WISH_TO_USE]' -sdk iphonesimulator9.2 -configuration Debug

Alternative could be to use https://github.com/facebook/xctool which works similar to xcodebuild
../<path>/xctool/xctool.sh clean build -workspace XYZ.xcworkspace -scheme ABC -configuration Debug -sdk iphonesimulator
I reported the same issue to Apple, it actually happens on any type of project when building from the command line using a "scheme" and specifying -sdk as simulator.
I looks like the ARCH and PLATFORM_NAME variables are incorrectly set even though we're specifying -sdk iphonesimulator. My current work around is to specify PLATFORM_NAME=iphonesimulator on top of the -sdk iphonesimulator flag on my xcodebuild command line.
Waiting to hear more from my bug report to Apple.
