iOS Linker command failed with exit code 1

So, I'm trying to compile this project. What's happening is that I'm getting this error code:

No I checked if there were any duplicates in the compile sources section. There was nothing.

And in the class which I had added, I had imported the .h file. Please help me.

The duplicate symbol error should show the symbols that have been duplicated.

This can happen by something like this

#import "MyViewController.m"

At any rate. Show the full error message.

Never mind. I looked at the full error message. Turns out I was importing a folder too many times. Thanks for the assistance!
