Build phase fails when SRCROOT contains a space character

[ashikase]

The script for the build phase Copy GoogleService-Info.plist fails when SRCROOT contains a space character, e.g., /path/to/folder of/Alfie-iOS.

Alfie-iOS/Alfie/Alfie.xcodeproj/project.pbxproj

Line 356 in 3b86301

shellScript = "if [ \"${ENABLE_PREVIEWS}\" = \"YES\" ]; then\n echo \"Building for Previews, ignore copy to avoid build loop issues.\"\n exit 0;\nfi\n\nif [ \"${CONFIGURATION}\" = \"Release\" ]; then\n SOURCE_CONFIG_PATH=$SRCROOT/Alfie/Configuration/Release/GoogleService-Info.plist\nelse \n SOURCE_CONFIG_PATH=$SRCROOT/Alfie/Configuration/Debug/GoogleService-Info.plist\nfi\n\nDESTINATION_CONFIG_PATH=\"${BUILT_PRODUCTS_DIR}/${PRODUCT_NAME}.app/GoogleService-Info.plist\"\n\necho \"Will copy ${SOURCE_CONFIG_PATH} to ${DESTINATION_CONFIG_PATH}\"\ncp $SOURCE_CONFIG_PATH $DESTINATION_CONFIG_PATH\n";

The last line of the script:

cp $SOURCE_CONFIG_PATH $DESTINATION_CONFIG_PATH

...should be:

cp "$SOURCE_CONFIG_PATH" "$DESTINATION_CONFIG_PATH"

(Technically, for this issue, quotes are only needed around the first variable.)
