Xcode CGRectZero Error

Question

I am getting the following error when compiling my code

      "_CGRectZero", referenced from:
          _CGRectZero$non_lazy_ptr in RootViewController.o
          _CGRectZero$non_lazy_ptr in SecondViewController.o
    ld: symbol(s) not found
    collect2: ld returned 1 exit status

Build failed (1 error)

could someone tell me a solution to solve this?

Answer 1

Sounds like your project is missing a framework.

Right-click on the Frameworks folder in your project's Groups & Files column, then select Add > Existing Frameworks...

Choose CoreGraphics.framework from the frameworks list.

Once you rebuild, this error should go away (unless it is something else).
