Can't Launch an Empty Game on iPhone [ LogPlayLevel: clang: error: linker command failed with exit code 1 (use -v to see invocation) ]

Hi,

I can’t launch my game on my iPhone.

This happens because I enable ‘Mobile Location Services - iOS Implementation’ plugin. I REALLY don’t get it.

Here are the error lines,

LogPlayLevel:   clang: error: linker command failed with exit code 1 (use -v to see invocation)

Please help. I have been trying to fix this issue more than a week now…
Thanks
