I'm developing an application in Xcode.
When I try to build, this error comes up:
ld: in /Users/theodore/Library/Developer/Xcode/DerivedData/Tower-bkpdifuqssebjdgurzmtirbxejnn/Build/Intermediates/Tower.build/Debug/Tower.build/Objects-normal/x86_64/TWRAppDelegate.o, file too small for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Stealing @martin-baulig's answer:
Try a full rebuild / clean. It's possible that the previous build has been abnormally aborted, leaving the TWRAppDelegate.o file corrupted or zero-size.
