Cannot find App Attest Capability in XCode

Question

According to the App Check Firebase Documentation, it is said to add the App Attest capability to your app. However, I am not able to find any such capability in XCode. Any insights on this?

Note: We have enabled capability in the provision profiles

A Firebase developer here.

Currently you need to set App Attest environment to production in your app entitlements file. You can achieve it by adding the key directly to the file or you can follow the steps below (relevant for Xcode 12.5):

1. Open Signing & Capabilities tab in the settings of your app target
2. Press + Capability button
3. Select App Attest(see screenshot)
4. Open the corresponding entitlements file usually named like YourAppTargetName.entitlements
5. Set value production for App Attest Environment key(see screenshot)

Sorry if the docs don't contain enough details, we will try to make them more clear.
