Xcode linker error: file too small for architecture x86_64

Question

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-b         


        

Answer 1

A clean rebuild didn´t in my case so i explain how i solved the problem:
- Removed reference to the file (don´t delete the file)
- Add the file to the project again and run

Answer 2

Quick way to fix error without complete cache clean:

1. Open file described in error (in case of this question TWRAppDelegate)
2. cmd + A
3. cmd + X
4. Rebuild - fail
5. cmd + V
6. Rebuild - succeed

Answer 3

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.

Answer 4

I usually add a space (could be any character for that matter) to the file in question, remove it and then save. Easier and quicker than a clean build.

Answer 5

rm -rf /Users/hostname/Library/Developer/Xcode/DerivedData

Answer 6

Since building a clean project may take way too long there is shorter way for those that have the access to the file that is corrupt in the cache:

• Delete the file (Remove reference)
• Build project
• Reinsert file
• Build project

Full version so you have no trouble finding the file:

• Find the file in Xcode project navigator
• Right click the file and press "show in finder" (opens a finder at the location where the file is)
• Select the file in Xcode and press backspace then click "Remove reference"
• Build project (it will fail but wait for it to finish)
• Reinsert file by dragging it from the finder into the same location you just deleted it
• Build project (should work now)
