XCode : library not found liPhone

Hi, I'm having the folowing problem on Xcode :

"ld: library not found for -liPhone-lib clang: error: linker command failed with exit code 1 (use -v to see invocation)"

I got the same error 5 months ago but i just remember it was a pain to solved it. I'm usually write all the error solution somewhere, but not that one.

This is my error message :

I'm using ios native plugin (stan asset), i tried the folowing things to fix it (without success) :

• tried to recompile many times.

• downgrade my unity version from 5.2 to 5.1.3.

• change the deployement target.

• removed and add again libiPhone-lib.a in the "linked Frameworks and Libraries" section.

• empty the "search Paths/Library Search Paths" field. (saw that solution somewhere)

-Update Xcode to xcode 7.0

• saw on an other project that i miss the "plugins" folder in the "libraries" folder, i copy the folder without any improvment.

I attach few screenshots of my project : -Architecture

I joined you some other screenshots here :

On the last one, this is the errors list when i'm not emptying the "library search paths" field.

I'm out of idea and there is not that much answer online on this error :s

Thanks Leo
