getting Apple Mach-O Linker Error - when tried to build [no error if i clean the project but it reappears again when i tried to built it!]

Question

Using core data, I was trying to create a simple dairy like application. But when I was trying to compile I am getting error like:

Apple Mach-O Linker Error 
Linker command failed with exit code 1 (use -v to see invocation)

To solve this, I deleted all extra code and clean the code and tried lots of way by following the link: Apple Mach-O Linker Error when compiling for device but still no solution.

Full error are the follwoing:

Go to Windows - Projects and hit delete for the derived data folder of your project. Then try again. — Fabio Poloni, Jul 14 '15 at 06:07
