Unity/GlesHelper.h file note found

Hi everybody!
I’m having some issue in Xcode when i try to compile and run my unity app on an iPhone 5 and on a simulator too: Lexical or Preprocessor error ‘Unity/GlesHelper.h’ file not found. 1836585--117780--pb.png
Before that when i tried to compile i got something like 200+ errors and i cleaned frameworks search paths and header search paths, so the 200+ errors disappeared and this one appeared. I tried it in Xcode 5.1.1, 6.0.1 and 6.1.1 and still the same problem. I’m using unity 4.5.5. Even when i create a new project in unity and try i get the same error. How can i get rid of this ?? Please help, i’m on this problem since 2 days. I want to notice that it works on the simulator before i put my iOS developer credentials and setup provisioning profile and app ID, but after that i doesn’t work on simulator

i cleaned frameworks search paths and header search paths
well - header search path should include Classes folder from trampoline

I get another error or the same error when i let header search paths
