Hi @ravipappyogi, it looks like that the linker is unable to find the definition of the Amplitude class in Objective-C. Could you check if you've followed the guides to install the dependency?

Hello
I have followed this step to add Amplitude

1. Navigate to File > Swift Package Manager > Add Package Dependency.
2. Enter https://github.com/amplitude/Amplitude-iOS into the search bar.
3. It automatically resolves to the latest version.

Also, not showing any error while I connected the iPhone device and run on that. Only getting a fail while I am trying to run in the simulator.

Undefined symbol: OBJC_CLASS$_Amplitude

Please let us know if anything manually adds any dependency or if any linker flag needs to add to build settings.

That's all you need to install amplitude. I'm not able to reproduce this in my local. There have several things you can check.

• Can clean build and rebuild to see if it fixes the issue?

  • Xcode -> Product -> Clean Build Folder and then build again.

• Please check after you installed Amplitude-iOS SDK, if there are 2 packages has been installed.
  
  Check if the Amplitude Framework has been auto-added into frameworks section.
  
  Check if Amplitude is under Link Binary With Libraries for your selected target.
  

• Please also try to clone this simple example to see if it can be built successfully.

Thanks.
