Firestore pod failing after update

Forums > Swift

I recentlly updated my pod files (pod update) which i have for over a year with my app.

I am now getting this error

ld: framework not found FirebaseInstanceID

I understand it cannot find this by framework, I am unsure why this would occur ?

I update my pods often, so the version my have been upgraded to 6.20 or 6.19 from the 6.18 version, I cannot see what would cause this breaking change.

My pods are shown below for reference, i'm developing for ios 13.1

pod 'Firebase/Analytics'
pod 'Firebase/Firestore'
pod 'Firebase/Auth'
pod 'Firebase/Storage'
pod 'Fabric', '~> 1.10.2'
pod 'Crashlytics', '~> 3.14.0'
pod 'Firebase/Functions'

I have removed all derived data multiple times, tried different devices, running the latest xcode of 11.3.1

Any ideas on what to try next? Thanks


Maybe try adding it through the build in package manager ? See if that changes anything (Xcode 11)


Firebase isnt able to use SPM yet ...

I just tried a full removal of the pods using

cocoapods-deintegrate cocoapods-clean

No luck, but i added a package (that I dont need) which i know contains FirebaseInstanceID

pod 'Firebase/Messaging'

Now it works, looks like they removed FirebaseInstanceID from where I was accessing it before because my pod file has never change


I can confim ths happened to me

I added Firebase/messaging and it works

this was the line of code that said "undefined identifier InstanceID" was not able to fix it using Firebase/Core alone

        InstanceID.instanceID().instanceID { (result, error) in
                if let error = error {
                    print("Error fetching remote instange ID: \(error)")
                else if let result = result {
                    Globals.Values.FCMToken = result.token


I had the same issue and posted it on Github. Here's the cause and the fix:
