kotlinlang

I'm trying to build an ios project in Xcode that uses KMP, it uses a Build Phase script that runs:
```cd "$SRCROOT/.."
./gradlew :shared:embedAndSignAppleFrameworkForXcode```
This has been working fine. Then today, my build started failing with:
```e: java.lang.NoClassDefFoundError: org.jetbrains.kotlin.resolve.calls.smartcasts.DataFlowInfo (initialization failure)```
I'm not sure what this means, or how to fix it?
Has anyone else run into this?

From my experience, it can be one of ~two~ three things:
• *Gradle Cache issue:* run `./gradlew clean` and try again running `./gradlew :shared:embedAndSignAppleFrameworkForXcode`
• *Check Kotlin Version Compatibility:* Verify that the Kotlin version used in your shared module's `build.gradle.kts` (or `build.gradle`) file is compatible with the Kotlin Gradle plugin version.
• *Xcode Version:* When developing KMP project with support to any iOS target, always make sure that your Xcode version is compatible with KMP which can be found here <https://kotlinlang.org/docs/multiplatform-compatibility-guide.html#version-compatibility>

I've eliminated some variables ... I can't even do a `gradlew clean` in the Multiplatform project folder. I get the same error. So it's not an Xcode thing. I've double checked my kotling and plugin versions. those are good.

I'm not sure what's going on here

<@U01B5C49R0R> Thanks for the tips. I have a fourth item to add to your list of possible things:

• Reboot your mac
:man-facepalming: I rebooted, and my builds work great.

Oh my god :man-facepalming: :sweat_smile:
