No known class method for selector 'setScreenName:screenClass:'

[jevarg]

Hello ! I added cordova-plugin-fcm to my cordova plugins, then I tried running the application on an iOS device but I got this error: No known class method for selector 'setScreenName:screenClass:' My application is currently using Ionic 4.3

Same problem after installing cordova-plugin-fcm

[jevarg]

I found out that my issue was that I was trying to use cordova-plugin-fcm and cordova-plugin-firebase at the same time.

So how did you end up resolving it, @jeangravier? I'm experiencing the same issue. Thanks.

I also experienced same issue, as jeangravier mentioned, I had cordova-plugin-fcm and cordova-plugin-firebase at the same time.

After remove two plugins, and reinstall cordova-plugin-fcm solved my issue.

ionic cordova plugin remove cordova-plugin-firebase ionic cordova plugin remove cordova-plugin-fcm ionic cordova plugin add cordova-plugin-fcm

Thanks, @taegyunum. Unfortunately, I needed both plugins (fcm for notifications, firebase for the database). If it was possible to do Firebase database transactions with fcm, that would've been ideal.

Hi, @ganiru,

I applyed fcm push service using cordova-plugin-firebase. I think you might not need to use both of it.

Using just firebase plugin would be okay.

When you apply FCM through firebase plugin, don't forget to use grantPermission() in iOS

Hi @taegyunum , can you show me how you applied fcm push using cordova-plugin-firebase. I want to remove the FCM plugin from the project entirely and rely on cordova-plugin-firebase for both database manipulation and push notifications. I can't find any docs on it. Thanks.
