Does Firebase Core v4+ now require a minimum of iOS 15?

[chornthorn]

Hello everyone,

I'm in the process of updating the FlutterFire plugins in my project and noticed a potential change in the minimum iOS version requirement for the firebase_core package.

While looking through the package source code, it appears the Package.swift file now specifies .iOS("15.0") as the minimum platform version.

Could the team please confirm if this is the new official requirement?

This is a significant change for us, as it would mean we need to update our app's minimum target and drop support for users on iOS 14 and older. We just want to be certain before making this change.

Thanks in advance for your help!
