How to specify specific source for a certain pod?

Although I believe this is harmless, warnings quite irk me. So I'm using a very specific version of TwilioChatClient together with TwilioClient. These two specific versions are what Twilio have been using in their sample projects.

Anyways, the warning when installing / updating pods:

[!] Found multiple specifications for TwilioChatClient (1.0.9): - /Users/XXX/.cocoapods/repos/master/Specs/7/d/e/TwilioChatClient/1.0.9/TwilioChatClient.podspec.json - /Users/XXX/.cocoapods/repos/twilio/TwilioChatClient/1.0.9/TwilioChatClient.podspec

My podfile:

project 'Proj/Proj.xcodeproj'

source 'https://github.com/CocoaPods/Specs'
source 'https://github.com/twilio/cocoapod-specs'

platform :ios, '10.0'
use_frameworks!

  target 'Proj' do

    pod 'TwilioClient', '~>1.2'     # Twilio Call Framework
    pod 'TwilioChatClient', '1.0.4' # Twilio Chat Framework


    target 'MobileMedTests' do
        inherit! :search_paths
    end

    post_install do |installer|
        installer.pods_project.targets.each do |target|
            target.build_configurations.each do |config|
                config.build_settings['SWIFT_VERSION'] = '4.0'
            end
        end
    end

  end

  target 'ProjUITests' do

  end

I think specifying two kinds of sources (which are both necessary) causes these warnings. Is there a way to put the specific source right beside the pod?

Solution

In fact, your problem comes from the fact that you have added the twilio repo to your pod source with this line :

source 'https://github.com/twilio/cocoapod-specs'

So when you type pod repo, you obtain something like :

master
- Type: git (master)
- URL:  https://github.com/CocoaPods/Specs.git
- Path: /Users/cyrille/.cocoapods/repos/master

twilio
- Type: git (master)
- URL:  https://github.com/twilio/cocoapod-specs
- Path: /Users/cyrille/.cocoapods/repos/twilio

And when you execute pod install, cocoa pods can find a version of this lib both in master's cocoapods repo and in twilio's one... which make the warning.

To remove this warning, remove this line from your Podfile :

source 'https://github.com/twilio/cocoapod-specs'

In a terminal execute the following commands :

pod repo remove twilio

and then :

pod update

You should get the following with no more warnings :
