Error in install firebase analytics in XcodeGen

Question

I'm using XcodeGen and tried to install firebase analytics . here the framework part on my project file

 3Party:
    type: framework
    platform: iOS
    settings:
      SWIFT_INCLUDE_PATHS: 3Party
      OTHER_LDFLAGS: $(inherited) -framework FirebaseAnalytics -framework FirebaseInstanceID -framework GoogleUtilities -framework FirebaseCore -framework FirebaseMessaging  -framework GoogleAppMeasurement -framework nanopb -framework Protobuf
      FRAMEWORK_SEARCH_PATHS: $(inherited) $(PROJECT_DIR)/Vendor/DropInSDKs/Frameworks/**
    configFiles:
      Debug: Configuration/Framework-iOS.xcconfig
      Release: Configuration/Framework-iOS.xcconfig
    sources:
      - path: PIA3P
        name: "3Party: Logic"
    dependencies:
      - target: Foundation

As soon as I add -framework FirebaseAnalytics I get these errors

Could anyone help me on this? Your help will be appreciated.

1. Download Firebase SDKs from https://firebase.google.com/docs/ios/setup#frameworks
2. Copy needed SDKs to some directory, eg Frameworks/
3. Use this template:

targets:
  FirebaseWrapper:
    type: framework
    platform: iOS
    transitivelyLinkDependencies: true
    requiresObjCLinking: true
    info:
      path: info.plist
    sources:
      - src
    settings:
      ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES: true
      OTHER_LDFLAGS: $(inherited) -ObjC
    dependencies:
      - sdk: libc++.tbd
      - sdk: libsqlite3.tbd
      - sdk: Storekit.framework
      - sdk: SystemConfiguration.framework
