Xcode 8 Pod update issue — Re-creating CocoaPods due to major version update [duplicate]

This question already has an answer here:

I installed the latest version Xcode 8 beta. My Project was developed by Swift 2.0. So I convert the project to Swift 3. So I update the pod file. But When I update the pod file I am getting error.

Pod file:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

pod 'Alamofire', '~> 3.4'
pod 'SwiftyJSON', :git => 'https://github.com/SwiftyJSON/SwiftyJSON.git'
pod "SwiftSpinner"
#pod "AFNetworking", "2.5.0"
pod 'HanekeSwift'

Error message:

Re-creating CocoaPods due to major version update. Analyzing dependencies [!] The dependency Alamofire (~> 3.4) is not used in any concrete target. The dependency SwiftyJSON (from https://github.com/SwiftyJSON/SwiftyJSON.git) is not used in any concrete target. The dependency SwiftSpinner is not used in any concrete target. The dependency HanekeSwift is not used in any concrete target.

NOTE: I already update the cocoapods using this command

sudo gem install cocoapods

To solve this issue delete the current pod file and create one using the terminal. Follow the below steps:

  1. Open Terminal
  2. Navigate to your Project Path
  3. Type pod init in terminal to create new pod file
  4. Open the newly created pod file and write the pod line which you want to install after target "TargetName" do and before end.
  5. Then type pod install in the terminal

Hope this helps!
