What works for me was deleting the pod.lock and run pod-install

[infostreams]

@dvetal @AayushiT the path in that new line is weird. What worked for me is the following:

change

pod 'Folly', :podspec => './node_modules/react-native/third-party-podspecs/Folly.podspec'

to

pod 'RCT-Folly', :podspec => '../node_modules/react-native/third-party-podspecs/RCT-Folly.podspec'
