Unity-Xcode Error: linker command failed with exit code 1 (use -v to see invocation)

I have been trying to test my Unity3D application on iPhone, and that requires me to open it through Xcode in order to run it on my iPhone device. However, I keep getting the same error message once I hit the Run button on Xcode. I have checked all the player settings on Unity, and also went through a lot of answers of similar questions and all of them did not help me solve the issue. Please help me find a solution as I cannot proceed with my work without it..

Here is the detailed error message:
