I’m having an issue running my Compose multiplatform app on a physical device.

When I run it on a simulator, it launches and works perfectly. When I attempt to build and run it for my physical iPhone 15 Pro Max I get a build error (see the thread).

The error log makes it seems like it is a FirebaseCrashlytics (or other Firebase products). But sometimes the error is different, related to the Kotlin IR.

My app is exported as a cocoapod, but I am importing the Firebase products via SwiftPM because I was experiencing issues with importing them as pods.

Using Kotlin 2.1.0, and Compose 1.7.1

Thanks for the link. Downgrading to 2.1.0-Beta1 seems to fix it for now
