Unable to open .xib file

Question

I am trying to run one of my old project. But getting following error

Command

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/ibtool failed with exit code 255

Also, I can access one of my .xib file. That is, whenever I try to open that particular .xib file Xcode closed.

How could I fix this error?

Answer 1

Sometimes this type of weird problem happens with xCode. Basic step would be:

1. Clean the project.
2. restart your xCode and Simulator.
3. reboot your computer.
