I'm following a tutorial on using Keychain here http://code.tutsplus.com/tutorials/securing-and-encrypting-data-on-ios--mobile-21263. I create a new project (universal not iPhone since the app I want to use it in will be universal) and add SSKeychain library and the RNCryptor library by copying the folders into my project.
However when I build I get an error from XCtestCase+RNCryptorVectorTests.h saying "Lexical or Preprocessor Issue 'XCTest/XCTest.h' file not found. I've searched google and stack overflow, but although other people have had issues with XCTest/XCTest.h, their solutions did not work for me. What should I do?
