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.
Creating a condition, which targets an app version via regular expression appears to be the only solution in this case.
For my app I use the following configuration:
Here, users who have versions 1.8.* and below receive an alternate version of a backend configuration parameter.
If you need to target only a specific version of the app, then a regular expression is not really necessary, so the approach that you took should work.
Alternatively, you can have far more control if you create a user audience based on app version, and then target the audience.
