Firebase pod 'InAppMessagingDisplay'

Question

I'm having difficulties installing Firebase new feature "In-App Messaging". When trying to run pod install on the project, I get this error:

[!] CocoaPods could not find compatible versions for pod "Firebase/InAppMessagingDisplay":
  In Podfile:
    Firebase/InAppMessagingDisplay

Specs satisfying the `Firebase/InAppMessagingDisplay` dependency were found, but they required a higher minimum deployment target.

These are the pod files in my project:

target 'MyProject' do
    platform :ios, '10.1'
    inhibit_all_warnings!
    use_frameworks!

    pod 'AlamofireImage', '~> 3.1'
    pod 'AKPickerView-Swift', :git => 'https://github.com/Akkyie/AKPickerView-Swift.git', :inhibit_warnings => true
    pod 'Firebase/Database', '~> 5.0.0'
    pod 'Firebase/Messaging', '~> 5.0.0'
    pod 'Firebase/Core'
    pod 'Firebase/Auth'
    pod 'Firebase/RemoteConfig'
    pod 'Firebase/InAppMessagingDisplay'
    pod 'Google/Analytics'
    pod 'Protobuf', '~> 3.2', :inhibit_warnings => true
    pod 'PromiseKit/CoreLocation', '~> 4.1'
    pod 'GoogleConversionTracking'
    pod 'FBSDKCoreKit'
    pod 'Branch'
    pod 'Fabric'
    pod 'Crashlytics'
    pod 'Apply'
    pod 'SnapKit', '>= 4.0.0'
    pod 'KeychainSwift', '~> 10.0'
    pod 'Bond'
end

I've read other questions in here and tried two different solutions. First I tried this: 1. pod repo remove master 2. pod setup 3. pod install Which didn't work. Got the same error.

Then I tried this: 1. pod repo update 2. pod deintegrate 3. pod install With the same result.

Have any of you experienced this and know a solution?

Answer 1

Reducing your Podfile to make it an MCVE, we can reproduce the issue with simply:

target 'MyProject' do
    pod 'Firebase/InAppMessagingDisplay'
end

So let's look at the specs:

→ https://cocoapods.org/pods/Firebase
→ https://github.com/CocoaPods/Specs/blob/master/Specs/0/3/5/Firebase/5.6.0/Firebase.podspec.json
→ Dependency on "FirebaseInAppMessaging": "0.11.0"
→ https://cocoapods.org/pods/FirebaseInAppMessaging
→ Redirection to https://firebase.google.com/docs/in-app-messaging/

Which means Firebase/InAppMessagingDisplay has a dependency on another spec that got REMOVED by Google. To demonstrate the removal:

$ pod repo update
$ pod search FirebaseInAppMessaging
[!] Unable to find a pod with name, author, summary, or description matching FirebaseInAppMessaging

But this spec exists, it was added nine days ago (Aug 16, 2018, 12:38 AM GMT+8) at: https://github.com/CocoaPods/Specs/blob/master/Specs/2/a/8/FirebaseInAppMessaging/0.11.0/FirebaseInAppMessaging.podspec.json. So some people may have it in cache.

I suggest you contact Google and ask them when they will restore FirebaseInAppMessaging. In the mean time, you can't use it.

You need higher versions of the following two Firebase SDKs to use in-app messaging

pod 'Firebase/Database', '~> 5.0.0'
pod 'Firebase/Messaging', '~> 5.0.0'
