将Firebase与Cocoapods集成在一个框架中

Question

我正在尝试将Firebase包含在链接到应用程序的框架目标中。当我将Firebase包含在框架目标中时，它不会编译应用程序，当我将Firebase包含到App和框架时，我会看到以下警告。

objc[25463]: Class FIRAAppEnvironmentUtil is implemented in both /Users/User/Library/Developer/Xcode/DerivedData/TestApp-bldxbgfroizmdggroxupwpsxowvt/Build/Products/Debug-iphonesimulator/AppUIKit.framework/AppUIKit (0x109078e98) and /Users/User/Library/Developer/Xcode/DerivedData/TestApp-bldxbgfroizmdggroxupwpsxowvt/Build/Products/Debug-iphonesimulator/AppKit.framework/AppKit (0x108effdb8). One of the two will be used. Which one is undefined.

以下是我的Pod文件

platform :ios, '9.0'

pod 'Firebase', '~> 3.6'
pod 'Firebase/RemoteConfig', '~> 3.6'

target 'AppKit' do
  use_frameworks!

  pod 'Alamofire', '~> 4.0'

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

end

target 'AppUIKit' do
  use_frameworks!
  # Pods for AppUIKit

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

end

target 'TestApp' do
  use_frameworks!

  # Pods for TestApp

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

end
