+## Remove Unused Architectures (for production only)
+
+The universal framework will run on both simulators and devices. But there is a problem, Apple doesn’t allow to upload the application with unused architectures to the App Store.
+
+Please make sure that you have "Remove Unused Architectures Script" added in your project while releasing your app to App Store.
+
+- Select the Project -> Choose Target -> Project Name -> Select Build Phases -> Press "+" -> New Run Script Phase -> Name the script as "Remove Unused Architectures Script".
+
+```javascript
+FRAMEWORK="Openpay"
+FRAMEWORK_EXECUTABLE_PATH="${BUILT_PRODUCTS_DIR}/${FRAMEWORKS_FOLDER_PATH}/$FRAMEWORK.framework/$FRAMEWORK"
+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[@]}"
+rm "$FRAMEWORK_EXECUTABLE_PATH"
+mv "$FRAMEWORK_EXECUTABLE_PATH-merged" "$FRAMEWORK_EXECUTABLE_PATH"
+```
+
+Thats all !. This run script removes the unused simulator architectures only while pushing the application to the App Store.
