Facing same issue, I've tried to put Build Libraries for Distribution = YES on LottieReactNative.xcodeproj but still the same error, anyone else got this error ?

@bouchja1 Ok, I think I've found a way to build, I've done the following steps and it's working:

• Remove Podfile.lock in ios directory
• Remove Pods directory in ios directory
• Run pod update in ios directory
• Got to Xcode -> Preferences -> Locations
• Check that the command line tools used is Xcode 12.0.0
• Under Derived Data: you have a path with a small arrow, click on the arrow and delete DerivedData from directory
• Run Product -> Clean
• Try yo build your project again

Hope that's going to help !

Thanks! This worked also for me. You probably know this but there is an alias to clear "Pods" directory. Instead of deleting the whole folder you can use the command:

pod deintegrate

And I am stopping to be a "smart" guy :D

@bouchja1 Haha no problem, I know that command but I'm not using it quite often it's why I'm doing it in the old basic way ^^

In case you build the app using the xcodebuild command and have a paramter -derivedDataPath, make sure to clear the files there.
