@christocracy sir every thing is fine and installed but no sucess

[christocracy]

• Terminate XCode

$ cd ios
$ rm -rf Pods
$ rm Podfile.lock
$ pod install

• Restart XCode
• XCode -> Product -> Clean Build Folder

It did not help. I did all those steps.

Do we need to add:

platform :ios, '9.0'

target 'SampleTarget' do
pod 'CocoaLumberjack'
end
