Not compatible with latest RxSwift

[erf]

I tried to do a pod install which resulted in the following:

[!] CocoaPods could not find compatible versions for pod "RxSwift":
  In snapshot (Podfile.lock):
    RxSwift (= 6.1.0)

  In Podfile:
    RxCocoa was resolved to 6.1.0, which depends on
      RxSwift (= 6.1.0)

    RxStarscream was resolved to 0.3, which depends on
      RxSwift (~> 2.5.0)

    RxSwift

My Podfile looks like this:

platform :ios, '10.0'

target 'MyApp' do
    use_frameworks!

    pod 'Firebase/Core'
    pod 'Firebase/Analytics'
    pod 'Firebase/Crashlytics'

    pod 'RxSwift'
    pod 'RxCocoa'

    pod 'RxStarscream'
end
