Different projects using ZXing have error after last Xcode update:
Error messages are:
- private field ‘cached_y_’ is not used
- Private field ‘bits_’ is not used
- Private field ‘cached_row_num_’ is not used
- Private field ‘dataHeight_’ is not used
Any compiler flag I have to set up?
Just add this flag
under ZXingWidget target -> Build Settings -> Other Warning Flags. Click the + button and paste the flag, clean and build again.
(No need to remove any other flag, just ignore unused private field warning)
