Multiple targets match implicit dependency for linker flags

Question

This is the full warning I get:

Multiple targets match implicit dependency for linker flags '-framework GTMSessionFetcher'. Consider adding an explicit dependency on the intended target to resolve this ambiguity. (in target 'Wishlists' from project 'Wishlists')

What is the reason for this and how can I resolve it? This also leads to this error.

I have a Main-App and a ShareExtension.

This is my podfile:

# Uncomment the next line to define a global platform for your project
platform :ios, '13.0'

target 'Wishlists' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for Wishlists

    pod 'Firebase/Analytics'
    pod 'Firebase/Auth'
    pod 'Firebase/Core'
    pod 'Firebase/Firestore'
    pod 'Firebase/Database'
    pod 'Firebase/Crashlytics'
    pod 'Firebase/Analytics'
    #pod 'TextFieldEffects'
    pod 'Hero'
    pod 'RevealingSplashView'
    pod 'LBTAComponents'
    pod 'lottie-ios'
    pod 'SwiftEntryKit', '1.2.3'
    pod 'FBSDKCoreKit'
    pod 'FBSDKShareKit'
    pod 'FBSDKLoginKit'
    pod 'GoogleSignIn'
    pod 'SkeletonView'
    pod 'SwiftSoup'
    pod 'Firebase/Storage'
    pod 'Kingfisher', '~> 5.0'
    pod 'KeychainAccess'


# add pods for desired Firebase products
# https://firebase.google.com/docs/ios/setup#available-pods 

end

target 'ShareExtension' do 
 
 use_frameworks!

    pod 'SwiftSoup'
    pod 'URLEmbeddedView'
    pod 'lottie-ios'
    pod 'Firebase/Analytics'
    pod 'Firebase/Auth'
    pod 'Firebase/Core'
    pod 'Firebase/Firestore'
    pod 'Firebase/Database'
    pod 'Firebase/Storage'
    pod 'Kingfisher', '~> 5.0'  

end

I also have two GoogleService-info-plist files, one for the Main-App and one for the Share Extension.

Any idea how I can resolve this issue?
