Different projects using ZXing have error after last Xcode update:

Error messages are:

  1. private field 'cached_y_' is not used
  2. Private field 'bits_' is not used
  3. Private field 'cached_row_num_' is not used
  4. Private field 'dataHeight_' is not used

Any compiler flag I have to set up?

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)
