Firebase SDK support in the Apple Silicon Unity Editor

Instructions

⚠️ Before proceeding, make sure your project is committed to source control and/or backed up! Proceed at your own risk.

NOTE: Firestore support is not included currently, as it depends on this fix making it into a release of firebase-ios-sdk, which it hasn't yet.

1. Download this repo
2. In your project, open the directory Assets/Firebase/Plugins
3. Copy the arm64 directory from the zip you downloaded into Assets/Firebase/Plugins
4. There should already be a directory named x86_64 in Assets/Firebase/Plugins. Delete it.
5. If your project was already open, you'll need to close and re-open it for the changes to take effect.

What is this?

If you both:

• Use Unity Editor on an Apple Silicon Mac
• Use the Firebase SDK in your Unity project

...and want to use the Firebase SDK functionality from inside the editor (e.g. Realtime Database)

...you've probably noticed that this it doesn't work, because the Firebase team has not yet provided a build of the Unity SDK compiled with arm64 Unity Editor support. Fortunately, the Firebase Unity SDK is open source, which allowed me to build the SDK with arm64 Unity Editor support 🎉
