ios - Submit to App Store issues: Unsupported Architecture x86

Question

So I am trying to use the Shopify API. When I archive the app and validate it then there are no issues but when I submit it to the app store then it gives me the following issues.

1. ERROR ITMS-90087: "Unsupported Architecture. Your executable contains unsupported architecture '[x86_64, i386]'."
2. ERROR ITMS-90209: "Invalid segment Alignment. The App Binary at SJAPP.app/Frameworks/Buy.framework/Buy does not have proper segment alignment. Try rebuilding the app with the latest Xcode version." (I am already using the latest version.)
3. ERROR ITMS-90125: "The Binary is invalid. The encryption info in the LC_ENCRYPTION_INFO load command is either missing or invalid, or the binary is already encrypted. This binary does not seem to have been built with Apple's Linker."
4. WARNING ITMS-90080: "The Executable Payload/..../Buy.framework is not a Position Independent Executable. Please ensure that ur build settings are configured to create PIE executables."

Answer 1

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 "$APP_PATH" -name '*.framework' -type d | while read -r FRAMEWORK
do
    FRAMEWORK_EXECUTABLE_NAME=$(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.
