Does updating to Firebase 8.x help?

[paulb777]

Also Analytics does not yet support macOS or Catalyst targets. See #4563 and #1732.

Hey @KyLeggiero. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

@paulb777 I can try updating Firebase on Monday.

And, this is neither a macOS nor Catalyst target; this is an iOS target running on an M1 Mac.

[paulb777]

Hmm, Catalyst is running an iOS target on a Mac - FirebaseAnalytics is only supported for iOS Simulators and iOS Devices.

Since there haven't been any recent updates here, I am going to close this issue.

@KyLeggiero if you're still experiencing this problem and want to continue the discussion just leave a comment here and we are happy to re-open this.

Mac Catalyst is using UIKit to compile and run native macOS apps.

I'm talking about taking iOS apps, compiled for iOS, doing literally nothing different with them, and running them on macOS. This is only possible on M1 Macs because they have the same exact processor architecture as iPhones and iPads. No recompiling, no targeting macOS, nothing different at all from any other iOS app.
