    It seems that you are compiling the same BlogTableItemCell class two times in different places of your code. This may happen in the following cases.

    • You have put the same class
      implementation into two different
      files;

    • You actually have just one
      implementation of this class, however
      you are also linking in your project a framework
      or library containing a class whose
      name is exactly the same of yours.

    Try finding in the whole project your class and make sure only one copy is available within your project.
