clang: error: linker command failed with exit code 1 (use -v to see invocation)

Hello! I'm using GeoFire (2.0.0) in the Swift project, after today's update pods when the project is going to Xcode shows clang: error: linker command failed with exit code 1 (use -v to see invocation) in the Geofire framework. Tell me, how can I fix this?

I install Geofire via Cocaopods as follows
pod 'GeoFire', :git => 'https://github.com/firebase/geofire-objc.git'

Update:
ld: framework not found nanopb
clang: error: linker command failed with exit code 1 (use -v to see invocation)

nanopb was introduced in Firebase iOS Version 4.0.4. You can set your dependency to pod 'Firebase', '4.0.3' to workaround the issue.

Hi @zgosalvez I set

Firebase

    pod 'Firebase/Core', '~> 4.0.3'
    pod 'Firebase/Auth', '~> 4.0.3'
    pod 'Firebase/Database', '~> 4.0.3'
    pod 'Firebase/Storage', '~> 4.0.3'
    # Push notification
    pod 'Firebase/Core', '~> 4.0.3'
    pod 'Firebase/Messaging', '~> 4.0.3'

But it doesn't help me

@zgosalvez I see this in the terminal

Using Firebase (4.0.4)
Using FirebaseAnalytics (4.0.2)
Using FirebaseAuth (4.0.0)
Using FirebaseCore (4.0.4)
Using FirebaseDatabase (4.0.0)
Using FirebaseInstanceID (2.0.0)
Using FirebaseMessaging (2.0.0)
Using FirebaseStorage (2.0.0)
Using GTMSessionFetcher (1.1.11)
Installing GeoFire 2.0.0 (was 2.0.0)
Using GoogleMaps (2.3.1)
Using GooglePlaces (2.3.1)
Using GoogleToolboxForMac (2.1.1)

@alexsanderkhitev, I only altered the 'Firebase' dependency. Paste this as is, as this will tell CocoaPods to install the specific version, not a variant of it.

pod 'Firebase', '4.0.3'
pod 'Firebase/Core'
pod 'Firebase/Auth'
pod 'Firebase/Database'
# ...

@zgosalvez thank you so much. Interesting situation with subsequent updates, it turns out if you use Geofire it will not work to update Firebase on versions higher than 4.0.3

You can fix this by adding nanopb as a library search path for geofire in the post_install phase.
I already had to do this for GoogleToolboxForMac:

post_install do |installer|
  installer.pods_project.targets.each do |target|
  if target.name == 'GeoFire' then
    target.build_configurations.each do |config|
      config.build_settings['FRAMEWORK_SEARCH_PATHS'] = "#{config.build_settings['FRAMEWORK_SEARCH_PATHS']} ${PODS_ROOT}/FirebaseDatabase/Frameworks/ $PODS_CONFIGURATION_BUILD_DIR/GoogleToolboxForMac $PODS_CONFIGURATION_BUILD_DIR/nanopb"
      config.build_settings['OTHER_LDFLAGS'] = "#{config.build_settings['OTHER_LDFLAGS']} -framework FirebaseDatabase"
    end
  end
end

Note that we're also planning on switching Firebase 4.x dependencies to the FirebaseCommunity Pod in #95

I get the same error: clang: error: linker command failed with exit code 1 (use -v to see invocation)

But none of these solutions worked for me.
Is there any other way to resolve this error?

In addition to coli88's answer, you will also need to add leveldb-library as a framework search path:

post_install do |installer|
  installer.pods_project.targets.each do |target|
  if target.name == 'GeoFire' then
    target.build_configurations.each do |config|
      config.build_settings['FRAMEWORK_SEARCH_PATHS'] = "#{config.build_settings['FRAMEWORK_SEARCH_PATHS']} ${PODS_ROOT}/FirebaseDatabase/Frameworks/ $PODS_CONFIGURATION_BUILD_DIR/GoogleToolboxForMac $PODS_CONFIGURATION_BUILD_DIR/nanopb $PODS_CONFIGURATION_BUILD_DIR/leveldb-library"
      config.build_settings['OTHER_LDFLAGS'] = "#{config.build_settings['OTHER_LDFLAGS']} -framework FirebaseDatabase"
    end
  end
end

Closing since this has staled. If you're still having build issues, please open a new issue and I'll address it.
