Submit to App Store issues: Unsupported Architecture x86

The problem is that the Buy framework contains a build for both the simulator (x86_64) and the actual devices (ARM).

Of course, you aren't allowed to submit to the App Store a binary for an unsupported architecture, so the solution is to "manually" remove the unneeded architectures from the final binary, before submitting it.

Daniel Kennett came up with a nice solution and provides this script to add to the build phase:

APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"# This script loops through the frameworks embedded in the application and# removes unused architectures.find "$APP_PATH" -name '*.framework' -type d | while read -r FRAMEWORKdo    FRAMEWORK_EXECUTABLE_NAME=$(defaults read "$FRAMEWORK/Info.plist" CFBundleExecutable)    FRAMEWORK_EXECUTABLE_PATH="$FRAMEWORK/$FRAMEWORK_EXECUTABLE_NAME"    echo "Executable is $FRAMEWORK_EXECUTABLE_PATH"    EXTRACTED_ARCHS=()    for ARCH in $ARCHS    do        echo "Extracting $ARCH from $FRAMEWORK_EXECUTABLE_NAME"        lipo -extract "$ARCH" "$FRAMEWORK_EXECUTABLE_PATH" -o "$FRAMEWORK_EXECUTABLE_PATH-$ARCH"        EXTRACTED_ARCHS+=("$FRAMEWORK_EXECUTABLE_PATH-$ARCH")    done    echo "Merging extracted architectures: ${ARCHS}"    lipo -o "$FRAMEWORK_EXECUTABLE_PATH-merged" -create "${EXTRACTED_ARCHS[@]}"    rm "${EXTRACTED_ARCHS[@]}"    echo "Replacing original executable with thinned version"    rm "$FRAMEWORK_EXECUTABLE_PATH"    mv "$FRAMEWORK_EXECUTABLE_PATH-merged" "$FRAMEWORK_EXECUTABLE_PATH"done

I used it and it worked perfectly.

EDIT: make sure you look at the modified script posted by Varrry, as this one has some minor issues.

Answer given by pAkY88 works, but I faced the same problem as Mario A Guzman in https://stackoverflow.com/a/35240555/5272316: once we cut off unused architectures we can't run script any more since it tries to remove not existing slices, because xcode doesn't re-embed binary every time.Idea was - just remove i386 and x86_64 slices when building for archive, so I modified script:

echo "Target architectures: $ARCHS"APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"find "$APP_PATH" -name '*.framework' -type d | while read -r FRAMEWORKdoFRAMEWORK_EXECUTABLE_NAME=$(defaults read "$FRAMEWORK/Info.plist" CFBundleExecutable)FRAMEWORK_EXECUTABLE_PATH="$FRAMEWORK/$FRAMEWORK_EXECUTABLE_NAME"echo "Executable is $FRAMEWORK_EXECUTABLE_PATH"echo $(lipo -info "$FRAMEWORK_EXECUTABLE_PATH")FRAMEWORK_TMP_PATH="$FRAMEWORK_EXECUTABLE_PATH-tmp"# remove simulator's archs if location is not simulator's directorycase "${TARGET_BUILD_DIR}" in*"iphonesimulator")    echo "No need to remove archs"    ;;*)    if $(lipo "$FRAMEWORK_EXECUTABLE_PATH" -verify_arch "i386") ; then    lipo -output "$FRAMEWORK_TMP_PATH" -remove "i386" "$FRAMEWORK_EXECUTABLE_PATH"    echo "i386 architecture removed"    rm "$FRAMEWORK_EXECUTABLE_PATH"    mv "$FRAMEWORK_TMP_PATH" "$FRAMEWORK_EXECUTABLE_PATH"    fi    if $(lipo "$FRAMEWORK_EXECUTABLE_PATH" -verify_arch "x86_64") ; then    lipo -output "$FRAMEWORK_TMP_PATH" -remove "x86_64" "$FRAMEWORK_EXECUTABLE_PATH"    echo "x86_64 architecture removed"    rm "$FRAMEWORK_EXECUTABLE_PATH"    mv "$FRAMEWORK_TMP_PATH" "$FRAMEWORK_EXECUTABLE_PATH"    fi    ;;esacecho "Completed for executable $FRAMEWORK_EXECUTABLE_PATH"echo $(lipo -info "$FRAMEWORK_EXECUTABLE_PATH")done

This script simply removes i386 and x86_64 slices from fat binary (if they exist) if running not for simulator (that means destination folder isn't like "Debug-iphonesimulator").

Sorry, I'm not familiar with shell scripts, so may be someone could write it more elegant way. But it works)

If you're using Carthage then you may experience this issue because the project is:

• Missing the carthage copy-frameworks build phase.
• Or the build phase doesn't include all the frameworks (incomplete list).

This action filters frameworks to a list of valid architectures (code).

Setting up the copy-frameworks build phase

From the Carthage building for iOS steps:

On your application targets’ “Build Phases” settings tab, click the “+” icon and choose “New Run Script Phase”. Create a Run Script in which you specify your shell (ex: bin/sh), add the following contents to the script area below the shell:

/usr/local/bin/carthage copy-frameworks

and add the paths to the frameworks you want to use under “Input Files”, e.g.:

$(SRCROOT)/Carthage/Build/iOS/Box.framework$(SRCROOT)/Carthage/Build/iOS/Result.framework$(SRCROOT)/Carthage/Build/iOS/ReactiveCocoa.framework

This script works around an App Store submission bug triggered by universal binaries and ensures that necessary bitcode-related files and dSYMs are copied when archiving.
