Legacy Build System works well.

same issue. Legacy Build Systems works. Removing the PNG files from the POD file / compiled sources within XCode also seems to temporarily resolve the issue.

I'm still having this issue, @diepnghitinh any fix?
Changing to Legacy Build is not solving my problem, i only get more errors.

same problem i cannot fix with legacy build.

[luis-cruzt]

I think that @diepnghitinh has to fix this, but i think he is inactive.

[luis-cruzt]

I think i found the solution that works for me:

It would be great if you guys can test it and tell me if it works for you:
