The dependency `AFNetworking (~> 2.5)` is not used in any concrete target

Question

I want to install AFNetworking but I have a problem, how can I fix and install? I used Getting Started with AFNetworking :

1. Download CocoaPods

sudo gem install cocoapods
pod setup

2.a. Create a Podfile

touch Podfile
open -a Xcode Podfile

2.b. And copy-paste this:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '7.0'
pod 'AFNetworking', '~> 2.5'

Solution

Add:

target 'MyApp' do
  pod 'AFNetworking', '~> 2.5'
end

See: https://guides.cocoapods.org/using/the-podfile.html

Then run pod install from the project directory.
