为什么我在 iOS（颤振应用程序）中收到 Firebase AppCheck 错误

Question

I've registered the Android and iOS versions of my Flutter app for AppCheck but it doesn't seem to work. I chose App Attest instead of DeviceCheck for iOS since it was more simple and AppCheck is initialized in the main function when the app starts. I followed all the steps in the docs but it's not working. Now that I'm trying to use Firestore I'm getting these errors:

Answer 1

Few points you could check

1. Download Google services info. Plist from firebase

2. Add it though xcode (very important) please don't add it directly to the ios folder

3. Add the reverse client id in info.plist

4. Make sure you call firebase. Initialise before you make any other call

5. If you downloaded the app from test flight to check please delete it and install the app from xcode once.
