Carthage versioning

[icedice]

[REQUIRED] Step 1: Describe your environment

• Xcode version: 12.4
• Firebase SDK version: 7.11.0
• Installation method: Carthage

[REQUIRED] Step 2: Describe the problem

The Carthage usage document (https://github.com/firebase/firebase-ios-sdk/blob/master/Carthage.md#carthage-usage) clearly states that

All Firebase components share the same version. Mixing and matching components with different versions may cause linker errors.

The newest version available seems to be 7.11 however for FirebaseAnalyticsBinary which always needs to be included the newest version is 7.4

What's going on here?

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Hi @icedice - sorry for the trouble. You can see an explanation at #7698 (comment), but the tl;dr is that Analytics switched to distribute the binary as an xcframework so we could support Apple silicon, but carthage doesn't have a release that supports xcframeworks yet.

We have another issue tracking Apple silicon support for Carthage that is tracked at #7039 that would solve this issue as well.

Thanks!
