Prevent "There are multiple dependencies with different sources" using CocoaPods - ios

Question

I use a combination of own and external pods in several projects. If I'm developing or updating a pod, I use a Podfile.local to avoid versioning/tagging every single change. The issue here, if that I must update Podfile to comment out every pod I'm using in Podfile.local to avoid errors.
Is there any way of telling cocoapods that should consider Podfile.local over Podfile when both files have the same pod to prevent this errors:
Analyzing dependencies [!] There are multiple dependencies with
different sources for Analytics in Podfile:
Analytics (HEAD)
Analytics (from ~/Documents/analytics_ios)
My Podfile:
source 'https://github.com/CocoaPods/Specs.git'
source 'http://gitlab.whatever.com/podfolder/cocoapods_ios.git'
platform :ios, '7.0'
# Allows per-dev overrides
local_podfile = "Podfile.local"
eval(File.open(local_podfile).read) if File.exist? local_podfile
pod 'Advertising/Dfp', :head
pod 'RSSParser', :head
pod 'DTCoreText'
pod "AFNetworking", "~> 2.0"
pod 'OurKeyboard', :head
pod 'VideoPlayer/GooglePrerollForAdMob', :head
pod 'Analytics', :head
pod 'AppVersioning', :head
My Podfile.local:
pod 'Analytics', :path => '~/Documents/analytics_ios'

The Podfile.local trick is no longer possible since CocoaPods 0.35 and was never officially supported.
See https://github.com/CocoaPods/CocoaPods/issues/2860

This same issue occurred when installing pod in Watch extension in existing application in Configuration :- Swift-3,Xcode-8.1 and Pod-version 1.0.1.
Existing Podfile With above error :
platform :ios, ‘10.0’ source 'https://github.com/CocoaPods/Specs.git'
use_frameworks!
target "DemoApp" do
pod 'SwiftQRCode'
pod 'Alamofire'
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['SWIFT_VERSION'] = '3'
end
end
end
target 'WatchExtension' do
platform :watchos, '2.0'
pod 'Alamofire'
pod 'SwiftyJSON'
end
pod install
Solution:
Create the shared definition which can be shared between main app bundle and watch OS extension :-
Updated podfile : source 'https://github.com/CocoaPods/Specs.git'
#Create common defination to share the library between app and extension
def shared_pods
pod'Alamofire'
pod 'SwiftyJSON'
end
target "DemoApp" do
platform :ios, '10.0'
use_frameworks!
shared_pods
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['SWIFT_VERSION'] = '3'
end
end
end
target 'WatchExtension' do
platform :watchos, '2.0'
use_frameworks!
shared_pods
end
So, Change in podfile has resolved above issue of "multiple dependencies with different sources....".
Need to update Library search path :-

My problem was that I had two same packages. One was deprecated other one was new just installed by me, but I didn't uninstall the deprecated package. So the new package was adding one dependency to my Podfile and the deprecated package was adding same the dependency, but from different source. I'd to uninstall the deprecated package and the error has gone.
