Mach-O Linker Error on Xcode 4.6

ios xcode xcode4.6

Just go to "Build Phases" -> "Compile Sources" and look for duplicate of classes.

Check if you have "*.m" files in your #import ! It appears that was my mistake...

Quit Xcode
Restart the System
Select Xcode -> Preferences -> Locations
In Locations, you will see 'Derived Data'. Click on the arrow icon right next to the path.
This will open a folder containing 'Derived Data', delete it.
Clean the Product and Run
if still not works then
Build Settings > Enable Bitcode > No
