Here I have a Mach-0 Linker error needed to be fixed. I found another question very similar to mine, but the solution is not feasible. How could I fix this?

UPDATE 1: Added duplicate symbols

It would help if you showed at least some of the duplicate symbols from the error. - rmaddy
I did that - please have a look at the error - gjys2000
Check if you have not deleted any of your main files. ".m" and also see if you have imported any files to your project. If you have tell me. - Xcoder

They all have the same basic pattern. Let's look at the first one:

duplicate symbol _OBJC_IVAR_$_SliderGaloreController.tileImageView in: /Users/GeoffSang/Library/Developer/Xcode/DerivedData/SliderGalore-game-gbmatdleglcvgscnctvgetfcneic/Build/Intermediates/SliderGalore-game.build/Debug-iphonesimulator/SliderGalore-game.build/Objects-normal/i386/SliderGaloreController.o /Users/GeoffSang/Library/Developer/Xcode/DerivedData/SliderGalore-game-gbmatdleglcvgscnctvgetfcneic/Build/Intermediates/SliderGalore-game.build/Debug-iphonesimulator/SliderGalore-game.build/Objects-normal/i386/SliderGaloreFlipsideViewController.o

The duplicate symbol is: _OBJC_IVAR_$_SliderGaloreController.tileImageView which is talking about the tileImageView member of the SliderGaloreController class.

The error states that this symbol is defined in two places: SliderGaloreController.o and SliderGaloreFlipsideViewController.o which were most likely created from your SliderGaloreController.m and SliderGaloreFlipsideViewController.mfiles.

Given the names, it would seem you have a typo in your SliderGaloreFlipsideViewController.m file or its .h file. Check both and be sure the @interface and the @implementation lines specify the right class name. Most likely the SliderGaloreFlipsideViewController.m or .h files specify the class SliderGaloreController instead of SliderGaloreFlipsideViewController.

That one fix should clear up most if not all of the errors.
