添加Analytics Pod后无法构建Objective-C模块Firebase，求解决方案

Hey there, I’ve dealt with this exact Firebase Analytics build issue a few times—let’s walk through some practical fixes to get your project running again:

• Do a full Pod reinstall
  Sometimes Pods get into a corrupted state. Close Xcode first, then run these commands in your project directory:

  pod deintegrate
  rm Podfile.lock
  pod install
  

  Once done, open your .xcworkspace file (not the .xcodeproj) and try building again.

• Verify your Podfile configuration
  Make sure your Podfile is set up correctly for Firebase. For most modern projects, this should work:

  platform :ios, '13.0' # Adjust to your project's minimum iOS version
  use_frameworks! :linkage => :static
  
  target 'YourAppTargetName' do
    pod 'Firebase/Analytics'
  end
  

  If you’re using an older setup, try adding use_modular_headers! instead of the static linkage line, then run pod install again.

• Check Xcode Build Settings
  Head to your target’s Build Settings and verify:

  • Header Search Paths includes $(inherited) (this ensures Pods’ headers are picked up automatically)
  • Build Active Architecture Only is set to No for both Debug and Release (sometimes this causes missing headers during compilation)

• Clean more than just DerivedData
  Delete DerivedData as you did before, but also clean the Xcode build folder with Cmd + Shift + K. For extra measure, run this terminal command to clear Xcode’s global cache:

  rm -rf ~/Library/Caches/com.apple.dt.Xcode
  

  Restart Xcode after doing this.

• Confirm GoogleService-Info.plist is properly added
  Make sure your GoogleService-Info.plist file is included in your app target:

  1. Select the file in Xcode
  2. Check the "Target Membership" panel on the right—your app target should be checked
  3. Also verify it’s listed under your target’s Build Phases > Copy Bundle Resources

• Test with a fresh project
  If none of the above works, create a brand new iOS project, add Firebase Analytics via Pods, and try building it. If that works, the issue is likely with your original project’s configuration (like conflicting build settings or outdated Xcode versions).
