iOS IPA file size - xcode-archive vs. xcodebuild command -

i have encountered problem size of ios application file (ipa) different between file built using xcode-gui archive action , 1 created using command-line build (xcodebuild command). size matters because we're getting following message apple:

the app binary listed below 44.6 mb when submitted it, 51.2 mb once processed app store. exceeds cellular network download size limit , require app downloaded on wi-fi

the ipa file built xcode 7mb smaller 1 built xcodebuild command.

the command line i'm using: /usr/bin/xcodebuild -sdk iphoneos -configuration release archs=armv7 valid_archs=armv7

problem solve adding following switches command line:

deployment_postprocessing=yes

strip_installed_product=yes

separate_strip=yes

copy_phase_strip=yes

i see settings in xcode project file , in gui - reason - running 'release' configuration without settings.
