Its because the iPhone simulator got duplicate .h & .m references. I struggled for hours for this bug.

My solution was simple. I copied the project to my pen drive and erased from computer memory.

Opened a new project, copied the storyboard and added the .h &.m files. Some errors fixed by selecting classes again in the storayboard view..
