You just have to install RN Permissions and make changes to the podfile and info.plist. Depending on what you need the permissions for, you get the pods. If you're not sure, do them all. You can find the code at https://www.npmjs.com/package/react-native-permissions. There are also some other things you may have to do-those I didn't talk about but are in the npm documentation in the link.

Thanks to @Raghav Herugu for helping me solve the problem

I was having the same issue with React Native 0.63.2.

The Solution was

1 - to update my cocopods version with

sudo gem install cocoapods --pre

2 - remove the following code from my pod file

pre_install do |installer|
  installer.pod_targets.each do |pod|
    if pod.name.eql?('RNPermissions') || pod.name.start_with?('Permission-')
      def pod.build_type;
        # Uncomment one line depending on your CocoaPods version
        Pod::BuildType.static_library # >= 1.9
        #Pod::Target::BuildType.static_library # < 1.9
      end
    end
  end
end

After that, I did a pod install and everything was working again.

At the moment, your Podfile is not configured to handle permissions. In your Podfile under your target, add the relevant lines of code for the permissions you are requesting:

target 'LocalMainStreet' do

  # react-native-permissions permission handlers
  permissions_path = '../node_modules/react-native-permissions/ios'

  pod 'Permission-AppTrackingTransparency', :path => "#{permissions_path}/AppTrackingTransparency.podspec"
  pod 'Permission-BluetoothPeripheral', :path => "#{permissions_path}/BluetoothPeripheral.podspec"
  pod 'Permission-Calendars', :path => "#{permissions_path}/Calendars.podspec"
  pod 'Permission-Camera', :path => "#{permissions_path}/Camera.podspec"
  pod 'Permission-Contacts', :path => "#{permissions_path}/Contacts.podspec"
  pod 'Permission-FaceID', :path => "#{permissions_path}/FaceID.podspec"
  pod 'Permission-LocationAlways', :path => "#{permissions_path}/LocationAlways.podspec"
  pod 'Permission-LocationWhenInUse', :path => "#{permissions_path}/LocationWhenInUse.podspec"
  pod 'Permission-MediaLibrary', :path => "#{permissions_path}/MediaLibrary.podspec"
  pod 'Permission-Microphone', :path => "#{permissions_path}/Microphone.podspec"
  pod 'Permission-Motion', :path => "#{permissions_path}/Motion.podspec"
  pod 'Permission-Notifications', :path => "#{permissions_path}/Notifications.podspec"
  pod 'Permission-PhotoLibrary', :path => "#{permissions_path}/PhotoLibrary.podspec"
  pod 'Permission-Reminders', :path => "#{permissions_path}/Reminders.podspec"
  pod 'Permission-Siri', :path => "#{permissions_path}/Siri.podspec"
  pod 'Permission-SpeechRecognition', :path => "#{permissions_path}/SpeechRecognition.podspec"
  pod 'Permission-StoreKit', :path => "#{permissions_path}/StoreKit.podspec"

end

You can read more about it in the react-native-permissions repo.

I had the same issue because I forgot to do:

npx pod-install
//or
cd ios
pod-install

The path changed. Now its ok. See below:

# permissions 
  pod 'Permission-BluetoothPeripheral', :path => "#{permissions_path}/BluetoothPeripheral/Permission-BluetoothPeripheral.podspec"
  pod 'Permission-Calendars', :path => "#{permissions_path}/Calendars/Permission-Calendars.podspec"
  pod 'Permission-Camera', :path => "#{permissions_path}/Camera/Permission-Camera.podspec"
  pod 'Permission-Contacts', :path => "#{permissions_path}/Contacts/Permission-Contacts.podspec"
  pod 'Permission-FaceID', :path => "#{permissions_path}/FaceID/Permission-FaceID.podspec"
  pod 'Permission-LocationAlways', :path => "#{permissions_path}/LocationAlways/Permission-LocationAlways.podspec"
  pod 'Permission-LocationWhenInUse', :path => "#{permissions_path}/LocationWhenInUse/Permission-LocationWhenInUse.podspec"
  pod 'Permission-MediaLibrary', :path => "#{permissions_path}/MediaLibrary/Permission-MediaLibrary.podspec"
  pod 'Permission-Microphone', :path => "#{permissions_path}/Microphone/Permission-Microphone.podspec"
  pod 'Permission-Motion', :path => "#{permissions_path}/Motion/Permission-Motion.podspec"
  pod 'Permission-Notifications', :path => "#{permissions_path}/Notifications/Permission-Notifications.podspec"
  pod 'Permission-PhotoLibrary', :path => "#{permissions_path}/PhotoLibrary/Permission-PhotoLibrary.podspec"
  pod 'Permission-Reminders', :path => "#{permissions_path}/Reminders/Permission-Reminders.podspec"
  pod 'Permission-Siri', :path => "#{permissions_path}/Siri/Permission-Siri.podspec"

They have mentioned about this issue in the documentation and also suggested a fix for the same and it works. Clearing the Xcode cache worked for me :)

Solution:

If you see a No permission handler detected error: Make sure that you have at least one permission handler set up. In some cases the Xcode cache needs to be cleared (Xcode -> Product -> Clean Build Folder)

iOS

By default no permission handler is installed. Update your Podfile by choosing the ones you want to check or request, then run pod install.

target 'YourAwesomeProject' do

  # …

  permissions_path = '../node_modules/react-native-permissions/ios'

  pod 'Permission-AppTrackingTransparency', :path => "#{permissions_path}/AppTrackingTransparency"
  pod 'Permission-BluetoothPeripheral', :path => "#{permissions_path}/BluetoothPeripheral"
  pod 'Permission-Calendars', :path => "#{permissions_path}/Calendars"
  pod 'Permission-Camera', :path => "#{permissions_path}/Camera"
  pod 'Permission-Contacts', :path => "#{permissions_path}/Contacts"
  pod 'Permission-FaceID', :path => "#{permissions_path}/FaceID"
  pod 'Permission-LocationAccuracy', :path => "#{permissions_path}/LocationAccuracy"
  pod 'Permission-LocationAlways', :path => "#{permissions_path}/LocationAlways"
  pod 'Permission-LocationWhenInUse', :path => "#{permissions_path}/LocationWhenInUse"
  pod 'Permission-MediaLibrary', :path => "#{permissions_path}/MediaLibrary"
  pod 'Permission-Microphone', :path => "#{permissions_path}/Microphone"
  pod 'Permission-Motion', :path => "#{permissions_path}/Motion"
  pod 'Permission-Notifications', :path => "#{permissions_path}/Notifications"
  pod 'Permission-PhotoLibrary', :path => "#{permissions_path}/PhotoLibrary"
  pod 'Permission-PhotoLibraryAddOnly', :path => "#{permissions_path}/PhotoLibraryAddOnly"
  pod 'Permission-Reminders', :path => "#{permissions_path}/Reminders"
  pod 'Permission-Siri', :path => "#{permissions_path}/Siri"
  pod 'Permission-SpeechRecognition', :path => "#{permissions_path}/SpeechRecognition"
  pod 'Permission-StoreKit', :path => "#{permissions_path}/StoreKit"

end

Added these in podFile

  permissions_path = '../node_modules/react-native-permissions/ios'
  pod 'Permission-LocationAlways', :path => "#{permissions_path}/LocationAlways/Permission-LocationAlways.podspec"
  pod 'Permission-LocationWhenInUse', :path => "#{permissions_path}/LocationWhenInUse/Permission-LocationWhenInUse.podspec"

Then run pod install For me this worked.

In your node_modules

go into this file -> react-native-permission, then find the file RNPermissions.m (could be inside the ios folder)

In this file Search for "No permission handler detected" and comment this line "RCTLogError(@"%@", message)"

Then you're good to go for now.
