xCode error

Dear all :

My xCode project run into linker error these two days. After googling and trying many suggestions, nothing works. So may anyone give a help about where to fix this problem. I used Unity 2017.4.13f1 to generate iOS xCode project. Really appreciate your support. Below is the error message generated from xCode Archieve (xCode 10.0).
