[SOLVED] React native fbsdk next error in XCode | Could not find or use auto-linked library

 After upgrading my react native fbsdk to react native fbsdk next, I encountered an error like this.

Could not find or use auto-linked library 'swiftCompatibility50'

.... and so on.

It has something to do with the swift files from a package you installed/linked. To solve this you have to create some sort of swift bridge by just creating an empty swift file in your xcode/workspace.

1. open XCode
2. create new file, select swift file
3. confirm "Create Bridging Header"
4. clean and build

Here are the guides that helped me.
