How to define firebase-remote-config parameters based on app version

Question

I need to distribute some settings based on the app version e.g. if app version equals "4.0.1" then a else b. I found the possibility to define a condition named "version" but the documentation says it is bound to the package name of the app and not the version or version code.

see here https://firebase.google.com/docs/remote-config/parameters

I tried it though specifying the app version through a "version" condition but it does not work. Any ideas on this would be much appreciated.

The main problem is that Remote config's "Version" is the build number and not the actual version number.

The way I found around this is you can add a "User Property" in Firebase like "app_version". Then when the app launches add the following code:

let version = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as! String
Analytics.setUserProperty(version, forName: "app_version")

You can then use this User Property in Remote Config as a condition and voila you can base some Remote Config value of of the version number. Note this will require the use of Firebase Analytics as well.
