Import Firebase in dynamic Swift framework (with/without Cocoapods) and import framework into app target

Question

Firebase for iOS is an Objective-C framework which recommends integration using Cocoapods. Here's how I'm trying to set it up:

I am running Xcode 8b6 on OS X 10.11.6. The app is being built with the iOS 10 SDK, targeting iOS 9.

MyApp is the regular (Swift) iOS app I want to use.

MyFramework is an embedded dynamic framework with the app, q. I would like all the Firebase code to be abstracted away into the framework, and therefore add Firebase to the MyFramework target in my Podfile:

# Uncomment this line to define a global platform for your project
# platform :ios, '9.0'

target 'MyApp' do
  # Comment this line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for MyApp
  target 'MyAppTests' do
    inherit! :search_paths
    # Pods for testing
  end
end

target 'MyApp' do
  pod 'Firebase'
  pod 'Firebase/Database'
  pod 'Firebase/Auth'
end

On running pod install, I am able to import Firebase in all .swift files in MyFramework. However, on using import MyFramework anywhere in my app, I get the error Missing required module Firebase.

Thinking this could be a Cocoapods issue, I started a fresh project and integrated Firebase manually, but ended up with the same issue. Is this a known issue? If so, are there any fixes for it?

In the podspec of MyFramework, add dependency of the Firebase pods. Also set the static framework flag as true. This is how your podspec should look:

*OTHER METADATA RELATED TO MYFRAMEWORK*
s.static_framework = true
s.dependency   'Firebase'
s.dependency   'Firebase/Database'
s.dependency   'Firebase/Auth'`
