Steps to reproduce:

I update Firebase SDK to 9.0.0, and tried to build my project on Xcode 13.0 and I'm getting 10 errors about Firebase Storage-
"Concurrency is only available in ios 15.0.0 or newer"
It seems like the Firebase already had a fix for it for ios users, but what about Unity users?
Here- firebase/firebase-ios-sdk#8685

Hi @shlighter,

Thanks for reporting this. I was able to reproduce this behavior on my end using the quickstart, and I'll relay my observations to the team.

I'll be marking this as a bug for now. You may refer to this thread for updates.

We've had similar issues in the past with version previous to Xcode 13.4 13.3.1. Currently the SDK requires XCode 13.4 13.3.1 as a minimum.

Could you check if this issue goes away if you update your Xcode version?

Thanks!

firebase/firebase-ios-sdk#8685 should definitely be included in the latest release: It's been fixed in Sep 2021 and staged in 8.8.0. The latest Unity SDK is using pod 9.1.0. So you issue might not related to that.

I am able to reproduce the same thing by just adding Storage pod. My current Xcode version is 13.1

According to this post, this seems requires Xcode 13.2 and above. Could you try and see if upgrading Xcode works for you?

My issue is regarding XCODE 13.0, not XCODE 13.2. (I can't update it because of other reasons)
Does firebase stop supporting XCODE 13.0?
