Actually, it looks like that isn’t the only package conflict. The following output comes from running a pod update
[!] CocoaPods could not find compatible versions for pod "CocoaLumberjack":
In Podfile:
ExpoKit/Core (from `http://github.com/expo/expo.git`, tag `ios/2.11.0`) was resolved to 33.0.0, which depends on
CocoaLumberjack (~> 3.2.1)
RNBackgroundGeolocation (from `../node_modules/react-native-background-geolocation-android`) was resolved to 3.0.6, which depends on

FBAudienceNetwork
ExpoKit/Core (from `http://github.com/expo/expo.git`, tag `ios/2.11.0`) was resolved to 33.0.0, which depends on

There are only pre-release versions available satisfying the following requirements:
'FBAudienceNetwork', '>= 0'
'FBAudienceNetwork', '= 5.1.1'
You should explicitly specify the version in order to install a pre-release version
CocoaPods could not find compatible versions for pod "FBSDKCoreKit":

CocoaPods could not find compatible versions for pod "Google-Mobile-Ads-SDK":
In Podfile:

Honest, I gave up and rebuilt the app in bare workflow (basically without expo) and had a lot of success. It’s hard when ExpoKit doesn’t keep up its deep versions.
Okay, in case it helps anyone else, what solved this problem for us was upgrading cocoapods to 1.7.2 (we previously were using 1.5.3). This made those version dependency errors go away, but then we got Podfile syntax errors about undefined method native_target. Then I used zanechua’s helpful explanation in undefined method native_target during post install · Issue #8138 · CocoaPods/CocoaPods · GitHub to fix up my Podfile syntax. Now the pod install works without any red errors. My new problem is getting GoogleUtilities/GULAppEnvironmentUtil.h file not found when trying to compile in XCode.
I still have the conflicts with FBSDK dependencies like this one:
EXFacebook (from `../node_modules/expo-facebook/ios`) was resolved to 5.0.1, which depends on
FBSDKCoreKit
ExpoKit/Core (from `http://github.com/expo/expo.git`, tag `ios/2.12.4`) was resolved to 34.0.0, which depends on
FBSDKCoreKit (= 4.40.0)
I am on Cocoapods version 1.7.5 and nothing helps, I have 1 week of struggling to update v32 to 33 or 34 and no success…
