    Just add this flag

    -Wno-unused-private-field
    

    under ZXingWidget target -> Build Settings -> Other Warning Flags. Click the + button and paste the flag, clean and build again.

    How to set compiler flags

    (No need to remove any other flag, just ignore unused private field warning)
