Build fails: Undefined symbol

[froston]

Describe the bug
The build fails and gives me 100 errors, all of them starting with Undefined symbol: ....

To reproduce

1. Install LaunchDarklySDK following the steps in the Getting Started guide
2. Build the app.

I found similar issue on StackOverflow

Expected behavior
Should make the build with success and SDK working in the app.

versions
launchdarkly-react-native-client-sdk 2.1.0
macOS Catalina 10.15.2
Xcode 11.3

Additional context

Thanks for any help!

Still unable to build without use_frameworks! with 2.1.0 too :/

@Titozzz didn't try use_frameworks! now it works, thanks!

Hi all, I'm still working on the documentation but to fix the undefined symbols error create a new, empty Swift file and then accept the prompt for an Objective C bridging header file. This should fix the error.

@froston @Titozzz Are both of you using iOS SDK version 4.3.2 in your Podfile?

[Titozzz]

@torchhound Yeah I'm aware of the trick to build Swift with the empty file.
Yes I'm using 4.3.2

[froston]

@torchhound Me too I'm using 4.3.2

(can confirm both of the tricks work)

What is the 2nd trick? Did the Objective C bridging header fix the undefined symbol error? @Titozzz
