I am using XCode 9 and when I create a Core Data project there are lots of missing pieces comparing to what we are shown in the tutorial videos…
Should we type them manually to match the video tutorial or what are we supposed to do here?
The code from here helped a lot -> http://discourse.djp3.net/t/core-data-assignment-with-xcode-8-2/999
but now I get a link error(more info in the link above)…
ld: 6 duplicate symbols for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
