GHUnit + XCode 4.2.1 : Not able to call method in real world app from GHUnit Target project

[Vikram]

Hi All,

I have successfully done the setup of GHUnit with Xcode 4.2.1 and could able to run sample test cases as well.

Now I want to call methods in real world app from GHUnit target project but always getting below syntax error.

"Lexical or Preprocessor Issue 'String' file not found."  I'm not able to overcome this compilation issue ?

It'll be really helpful if you can let me know how to solve this issue ?

Am I missing something while doing Target project setup ?

Thanks in advance.

Regards,

Vikram
