"RCTBundleURLProvider.h" file not found - AppDelegate.m

Solution 1:

xcode Product->Scheme->Manage Schemes click '+' at the Target to select "React" and set the React is shared.

Solution 2:

Delete node modules, then run npm install (or better yet yarn) and after everything has finished downloading, run react-native upgrade which should give you the option to replace old files with the template ones, by doing so you re-link your native dependencies in react-native which should fix your problem. Of course don't forget to clean your project in Xcode.

Solution 3:

For all those are using React Native 0.40.0 or higher, Header Imports have a major change from RN 0.40.0 and result in lots of .h file not found errors. react-native-git-upgrade fixed the issue for me while in debug but build fails in release/archive.

I am using RN 0.42.3 with cocoapods and Xcode 8.2.1

To completely fix this go to Xcode>Product>Scheme>Edit Scheme>

Untick Parallelize Build
Click on + button in Targets and add React
Drag the added React to top of the List in Targets.

Now clean the project and build

Solution 4:

None of the other suggestions were fixing my error but this one did it.

1 - Create Podfile

Create a file named ios/Podfile inside your react-native app with the following contents:

# You Podfile should look similar to this file. React Native currently does not support use_frameworks!
source 'https://github.com/CocoaPods/Specs.git'

platform :ios, '8.0'

target '<YOUR_APP_NAME>' do
  # Fixes required for pod specs to work with rn 0.42
  react_native_path = "../node_modules/react-native"
  pod "Yoga", :path => "#{react_native_path}/ReactCommon/yoga"
  pod "React", :path => react_native_path, :subspecs => [
    'Core',
    'RCTActionSheet',
    'RCTAnimation',
    'RCTGeolocation',
    'RCTImage',
    'RCTLinkingIOS',
    'RCTNetwork',
    'RCTSettings',
    'RCTText',
    'RCTVibration',
    'RCTWebSocket'
  ]

  pod 'GoogleMaps'  # <~~ remove this line if you do not want to support GoogleMaps on iOS

# when not using frameworks  we can do this instead of including the source files in our project (1/4):
#  pod 'react-native-maps', path: '../../'
#  pod 'react-native-google-maps', path: '../../'  # <~~ if you need GoogleMaps support on iOS
end

2 - Install Podfile

Run the command pod install from inside the ios folder.

3 - Reset XCode

Restart XCode and the error should be gone.
