Can't build Xcode project since 10.2.1

Hi all

Since the recent Xcode upgrade, I've had no success building my game. I get the following error and I'm not really sure how to fix this:

ld: library not found for -lPods-Super Dungeon Delvers

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any help appreciated, cheers.

As a test, I tried to build a copy that I have successfully built in the past. It also failed with the same error.
