iOS linker related problem - Undefined symbols for architecture armv7

[naviln]

Hi buddy,

First off, thanks for writing this great library!

I was wondering if you could help me with a problem though.

The code works fine on Windows, but I am having problems getting my iOS (xCode) project to build.
Note: For the xCode build, I made sure to copy your Clipper.m class to the xCode Classes directory.
I'm also using Unity 2019.2.10f1.

I'm getting what i think is a linker related problem, with the below error message when compiling a build:

**Undefined symbols for architecture armv7:**

**ld: symbol(s) not found for architecture armv7**
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Do you have any suggestions on what I am doing wrong? How can i fix this?

Cheers!
