Following the installation guide step by step during the build I get an error "duplicate symbols....". How to fix it?

Tell me the way to fix that. Thanks !

@anhhtz doesn't seem like he's interested in helping anyone. have you found anything in the meantime? :D

I believe the docs are wrong with "drag the SDK files into the project". it seems that Pods already do that for you

Ok. So does that mean, if you pod install - by mistake, you should maybe remove the framework you dragged? I noticed it was indeed added to cocoapods framework folder. If I find a solution or a set of steps, I will come back here.

I don't exactly remember but in the docs there was a step where is says you need to drag the SDK files into your project. this is completely false because if i rememebr correctly "pod install" does it for you automatically.

wallycarvalho commented 3 years ago

Alright, if anybody ran pod install by mistake (event after the warning stated before you started the quickstart tutorial) here is what worked for me:

The first step during the quickstart tutorial is to drag the frameworks (4 in total) to your Frameworks folder.
If you ran pod install after and get duplicate symbols check your framework folder under the Pods(Corekit and Sharekit for instance). You will also see the Frameworks in there. My assumption is that these are causing the duplicate symbols (which kinda makes sense because if you look at the errors they point to the newly added frameworks).
Next, just delete those 4 framework folder that were added during the Drag action.

Again, there is a big warning and if you didn't pod install and followed all the other steps... you should be fine.
