Check and Remove Unsupported Architecture [x86_64, i386] in IPA / Archive

Question

Problem:

While submitting the app to the App Store the following error is reported:

Unsupported Architecture. Your executable contains unsupported architecture '[x86_64, i386]

Questions:

1. How can the above error be resolved ?

2. How can I check the architectures used by the archive or IPA ?

3. How can I ensure that the Release archive doesn't include x86_64 and i386 (simulator architectures).

   • Is it only possible through script or is there is a setting in Build Settings or else where ?

Answer 1

Apple has started complaining if app contains simulator architectures during distribution.

How can the above error be resolved ?

Solution :

Add below code in run script of Project target, this remove the simulator architecture (x86_64 and i386) from your app on building process:

Shell :

/bin/sh

Code :

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

Solution :

There one more solution, if you wish to do it only once. But be careful though as after doing following steps, you will not be able to run app on simulator. Do it just before deploying the app on Testflight/App-store.

Go inside the your ProjectFramework.framework folder of your project from terminal. Run following commands:

lipo -remove i386 ProjectFramework_SDK -o ProjectFramework_SDK 
lipo -remove x86_64 ProjectFramework_SDK -o ProjectFramework_SDK

Check the architectures from framework?

$ lipo -info PathToProject/ProjectName.framework/ProjectName

Output will be : → Architectures in the fat file: ProjectName are: i386 x86_64 armv7 arm64
