ios - ld: library not found for -lBolts using cocoapods

Question

everybody

The problem that I am having is that I can't compile my app because I got the following error:

ld: library not found for -lBolts
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I have my XCode project configured to use cocoapods and this is my list of pods:

pod 'Google/Analytics', '~> 1.0.0'
pod 'AFNetworking', '~> 2.0'
pod 'XCDYouTubeKit', '~> 2.4.0'
pod 'FBSDKCoreKit'
pod 'FBSDKShareKit'
pod 'FBSDKLoginKit'
pod 'Parse'
pod 'ParseUI'
pod 'ParseFacebookUtilsV4'
pod 'ParseTwitterUtils'

This is the output of the command pod install:

I had two problems:

1. The first problem was that I was building my original YourApp.xcodeproj Xcode project file.

   According to react-native:

   From now on open YourApp.xcworkspace instead of YourApp.xcodeproj in Xcode.

   So I had to switch to the new YourApp.xcworkspace generated by Cocoapods on pod init (or whatever generated it).

2. The README of react-native project doesn't mention that if you have previously added Facebook SDK into YourApp.xcodeproj's Frameworks folder according to the step 4. Add the SDK to your Xcode Project of Facebook SDK for iOS - Getting Started tutorial, then you should remove those references, because Cocoapods will pull the FB SDK code into Pods folder, so you no longer need to reference FB SDK separately. Otherwise, Xcode tries to build according to the settings and instructions of the Cocoapods, but finds FB SDK which has binaries that are "not a dylib".

   Eventually, your Frameworks folder should have the only libPods-YourApp.a file.

   Clean, then build the project. It should work.
