Cocoapods is installing old Pod version - ios

Question

I'm using RxSwift and other Rx-pods in my app, according to my Podfile.lock I use RxSwift (3.2.0), but now I want to update the Pods to the latest versions.
So I remove the 4 Rx..-pods that I use from my Podfile, and run pod install, this removed the pods from the project and the Podfile.lock. The I re-add the 4 Rx..-pods and run pod instalagain. This installs RxSwift 2.6.1... Why? - I'm expecting it to install the newest stable version of RxSwift, something like 3.6.1..
I tried removing everything listed by: gem list --local | grep cocoapods and reinstalling cocoapods by running: gem install cocoapods
I also tried running pod repo update without success.
I also tried just running pod update, without uninstalling the Pods first, also same outcome.
I suspect this to be an issue with my cocoapods-gem, not The Rx-pods..
Edit added Podfile:
source 'https://github.com/CocoaPods/Specs.git'
# Uncomment this line to define a global platform for your project
platform :ios, '9.0'
# Uncomment this line if you're using Swift
use_frameworks!
target 'MyApp' do
pod 'BrightFutures'
pod 'Alamofire'
pod 'MBProgressHUD'
pod 'Fabric'
pod 'Crashlytics'
pod 'Analytics', '~> 3.0'
pod 'SwiftyJSON'
pod 'Eureka', '~> 2.0.0-beta.1'
pod 'RxCocoa'
pod 'RxSwift'
pod 'INTULocationManager'
pod 'ReachabilitySwift', '~> 3'
pod 'RxSwiftExt'
pod 'RxMKMapView'
end
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['SWIFT_VERSION'] = '3.0'
end
end
end

Answer 1

You could try the following:
Clearing CocoaPods' cache:
rm -rf "${HOME}/Library/Caches/CocoaPods"
rm -rf "`pwd`/Pods/" (while in your project's dir)
Finally pod update
If you are using 0.38.0.beta1, you can just use pod cache clean
Regenerate everything:
rm -rf ~/Library/Caches/CocoaPods
rm -rf Pods; rm -rf ~/Library/Developer/Xcode/DerivedData/*
pod deintegrate; pod setup; pod install
Set the version
pod 'RxSwift', '~> 3.0' # last version is 3.6.1

Answer 2

The latest release of RxMKMapView needs RxCocoa 2.x.x. Apparently they need to update the Podspec, to allow RxCocoa 3.x.x. They did this in a commit, but it was never uploaded to cocoapods (or however that works). So I solved the problem by getting the pod from that commit. Because the pod RxCocoadidn’t have a minimum version requirement, cocoapods would just get latest version of RxCocoa that satisfied pod RxMKMapView, which was an old version (2.x.x). This was why I though something was wrong with my Cocoapod install, turns out it’s important to declare minimum versions of the wanted pods.. This solved the problem:
pod ‘RxCocoa’, ‘~> 3’
pod ‘RxSwift’, ‘~> 3’
pod ‘RxMKMapView’, :git => ‘https://github.com/RxSwiftCommunity/RxMKMapView.git', :commit => ‘6b86c6a’
