Linker Error - class doesn't exist anymore

Getting the following linker error, in XCode and my project won't build. Problem is, the class doesnt exist anymore. I had a class named SomeOtherViewController but then deleted it. When I try and build 开发者_运维技巧its somehow still looking for it.

Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_SomeOtherViewController", referenced from:

How can I solve this?

Cheers,

1. Clean your builds.
2. Build again.

To clean do one of following:

1. Product -> Clean
