Problems getting CocoaPods working with React Native

Question

Description

I installed CocoaPods and opened the xcworkspace in Xcode but I get this error when trying to build:

Reproduction

Managed to reproduce it with a fresh project:

1. react-native init
2. react-native run-ios (running ok)
3. pod init && pod install (no dependencies added)
4. Build from XCode (or react-native run-ios)

Here is an example project (just run npm install and react-native run-ios to reproduce with this example project) CocoaPodsFailure.zip

Additional Information

• React Native version: 0.36.1
• Platform: iOS
• Operating System: MacOS

Answer 1

Had the same problem. Tried various things before I landed on a post that suggested to add the line:

use_frameworks

to your PodFile. It allowed me to get past the link errors.
