Hi, After updating to the latest macos beta, I'm getting the following error on my CMP project when I try to run the iOS App. Anyone having an idea how to fix this?

Copy code

I’m running into this too. I thought it might be because I was using Xcode 26b1 on macOS 26b2, but upgrading didn’t change anything. I also tried deleting Derived Data and various other build folders with no luck. For me the failing pod is Bugsnag.

After upgrading to Kotlin 2.2.0, I'm getting now the following error and I also used Xcode 26b1 on macOS 26b2:

@Zachary Wander could you fix it already?

Unfortunately not. It stopped happening for me on its own

Jimmy Nelle

Did you downgrade Xcode or what did you to fix it?

Like I said, I don't know why it started working again
