Resolving Unsupported Architecture Errors When Submitting to the App Store

Resolving Unsupported Architecture Errors When Submitting to the App Store

28 February 2025 Stephan Petzl Leave a comment Xcode

When submitting an app to the App Store, developers may encounter errors related to unsupported architectures, such as ERROR ITMS-90087, which indicates the presence of unsupported architectures like x86_64 and i386 in the app’s binary. This guide provides a comprehensive solution to address these issues effectively.

Understanding the Problem

The root of the problem often lies in the inclusion of simulator architectures within the app’s binary. These architectures, such as x86_64 and i386, are meant for testing purposes on simulators and are not supported by the App Store for actual device deployment.

Solution: Removing Unsupported Architectures

To resolve this issue, you need to manually strip out the unsupported architectures from the final binary before submission. Here’s a step-by-step guide on how to do this:

Step 1: Add a Run Script Phase in Xcode

  • Open your project in Xcode.
  • Navigate to the Build Phases tab of your target settings.
  • Click the + button and select New Run Script Phase.
  • In the script area, add the following code to remove the unsupported architectures:

  APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"

  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"

    EXTRACTED_ARCHS=()

    for ARCH in $ARCHS
    do
      lipo -extract "$ARCH" "$FRAMEWORK_EXECUTABLE_PATH" -o "$FRAMEWORK_EXECUTABLE_PATH-$ARCH"
      EXTRACTED_ARCHS+=("$FRAMEWORK_EXECUTABLE_PATH-$ARCH")
    done

    lipo -o "$FRAMEWORK_EXECUTABLE_PATH-merged" -create "${EXTRACTED_ARCHS[@]}"
    rm "${EXTRACTED_ARCHS[@]}"

    mv "$FRAMEWORK_EXECUTABLE_PATH-merged" "$FRAMEWORK_EXECUTABLE_PATH"
  done

Step 2: Ensure Proper Build Settings

  • Verify that your target’s build settings are configured correctly to ensure that the script is executed after embedding the frameworks.
  • Make sure the script is positioned after the embed frameworks step in the build phases.

Additional Considerations

In some cases, using tools like Carthage may require additional configuration to ensure frameworks are embedded correctly. Ensure that the carthage copy-frameworks script is executed to manage architecture slicing appropriately.
