Hi, has anybody looked into this one? I am having the same issue integrating this library into my project.

Hi guys, providing a bit more comments here as the ones provided by @erikahumada to @davodesign84

Here is a script I just ran trying to understand the problem in a brand new project:

react-native init mixpanelTest

cd mixpanelTest

yarn add react-native-mixpanel

react-native link react-native-mixpanel

react-native run-ios

The outcome of this is

... build stuff...

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_Mixpanel", referenced from:
      objc-class-ref in libRNMixpanel.a(RNMixpanel.o)
ld: symbol(s) not found for architecture x86_64

Here is the info of my setup:

react-native -v
> react-native-cli: 2.0.1
> react-native: 0.54.3

And my package.json has the following dependencies

"dependencies": {
    "react": "^16.3.0-alpha.1",
    "react-native": "0.54.3",
    "react-native-mixpanel": "^0.0.16"
  },

Uhms... I think I found the source of my issues... I am missing the installation of the SDK for iOS.

@rodrigoelp did you add the SDK manually/with pods/link? I added manually and I'm still getting an undefined symbols error.

I added with pods and still get the same error
