As the variation on option 2 suggested here, one can use a Run Script Phase. The cons is that it will be dynamically switch to the run destination runtime (unless run without build is used with a different run destination). if [ $XCODE_VERSION_ACTUAL -gt 1640 ]; then echo >&2 "error: time to remove 'libswiftWebKit' patch" exit 1 fi DYLD_FALLBACK_LIBRARY_PATH=$(xcrun simctl list devices -v | awk -v device_uuid=$TARGET_DEVICE_IDENTIFIER '/^--/ { RUNTIME=$0 } $0 ~ device_uuid { print RUNTIME }' | sed -E 's/.*\[(.*)\].*/\1/') DYLD_FALLBACK_LIBRARY_PATH="$DYLD_FALLBACK_LIBRARY_PATH/Contents/Resources/RuntimeRoot/System/Cryptexes/OS/usr/lib/swift" ln -sf "$DYLD_FALLBACK_LIBRARY_PATH/libswiftWebKit.dylib" "$BUILT_PRODUCTS_DIR/libswiftWebKit.dylib"
