Problems after upgrading to Xcode 10: Build input file cannot be found

Question

I upgraded my Xcode SDK to version 10 last night and then find I cannot build.

I\'m getting this error:

Build input file cannot be found: \

Answer 1

The "Legacy Build System" solution didn't work for me. What worked it was:

1. Clean project and remove "DerivedData".
2. Remove input files not found from project (only references, don't delete files).
3. Build (=> will generate errors related to missing files).
4. Add files again to project.
5. Build (=> should SUCCEED).
