firestore build error on visionOS

[AdiTexas]

I am getting this build error for Apple Vision Pro as target (builds for other Apple platforms). The suggested step (open --env ...) leads to more build errors - mentioned below the rig error below.

Any guidance?

"Firebase Firestore's binary SPM distribution does not support visionOS. To enable the source distribution, quit Xcode and open the desired project from the command line with the FIREBASE_SOURCE_FIRESTORE environment variable: open --env FIREBASE_SOURCE_FIRESTORE /path/to/project.xcodeproj. To go back to using the binary distribution of Firestore, quit Xcode and open Xcode like normal, without the environment variable."

More build errors after doing above:

Missing package product 'abseil'
Missing package product 'gRPC-cpp'

Perplexity suggests using only auth, core etc - but I need firestore for my app.

"Clean Up Unnecessary Dependencies

In your Xcode “Package Dependencies” list, ensure you do not reference unsupported packages for visionOS:

Remove abseil, gRPC-cpp, and any Firebase product that brings these in (most commonly Firestore or Storage).

Keep only FirebaseCore, FirebaseAuth, and any package that is specifically documented as supporting visionOS as of late 2025."

If you've used CocoaPods in the project before, do a pod deintegrate. For reference the CI that verifies the build is at https://github.com/firebase/firebase-ios-sdk/blob/main/.github/workflows/firestore.yml#L472.

If you're still stuck, create an issue with full reproduction steps including Firebase and Xcode versions.

Thank you, got it to work with the FIREBASE_SOURCE_FIRESTORE option for visionOS. Hopefully the binaries option will be supported soon too.
