Hi,

Just a head up that cocoapods is in "Maintance mode"

https://blog.cocoapods.org/CocoaPods-Support-Plans/

E.g. I maintain Unity, React Native, Flutter etc. A lot of these projects will (and should) be migrating to Swift Package Manager with time. As specified above, we are not breaking anything but bugs you may raise are unlikely to get fixed.

We do have support for CocoaPods already, so I'm not sure why this task is open. But we ran into another pipeline issue with CocoaPods in release 2.4.0 and later. I believe it's caused by this GitHub Actions issue but applying the workaround of changing the environment to macos-15 didn't succeed.

So to me, the question rather is: Do we want to drop CocoaPods support officially now that CocoaPods itself is in maintenance mode as recently announced in their blog post?

Are people using TelemetryDeck through CocoaPods? And what are reasons why they can't migrate?
