Show us the code you are using?

Not relevant, code itself is very basic usage of react-native-pdf, almost directly from the docs.

Go to ios folder then remove

Pods & Podfile.lock
run pod install
Rebuild project

[Jussinevavuori]

Thank you, however this has not fixed it. Reinstalling pods and rebuilding the project did not work, neither did a completely fresh iOS rebuild after deleting the /ios folder.

I had this issue and i needed to install react-native-blob-util after updating

[Jussinevavuori]

Doing these in succession did it! For further reference, if anyone else is having issues with this, do this:

# install latest version of react-native-blob-util
npm install react-native-blob-util@latest

# remove and reinstall pods
cd ./ios
rm -rf Pods
rm Podfile.lock
pod install

# run your project as usual
expo run ios # or other command
