Not building in Xcode to run on device

Getting the following error when I try to run on my device:

```
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
```

Tried a bunch of things to change settings, etc. based on Google searching but nothing worked, and errors are only coming from this Pod out of all my pods.

Xcode 10.1
Swift 4.2
