I'm trying to setup a KMM module with Couchbase Lite as a platform dependency for both Android and iOS. I'm running into errors getting this to work with CocoaPods for iOS:
Exception in thread "main" java.lang.Error: /var/folders/pv/3_5xn0dd0v5bf6sxbfcsq_wr0000gn/T/7009311365357251921.m:1:22: error: expected ';' after module name

The generated 7009311365357251921.m file is not present at that path afterwards, which makes this difficult to debug.
build.gradle.kts:
plugins {
kotlin("multiplatform") version "1.4.21"
kotlin("native.cocoapods") version "1.4.21"
id("com.android.library")
}
...
kotlin {
android()
ios()
cocoapods {
summary = "TBD"
homepage = "TBD"
ios.deploymentTarget = "9.0"
pod("CouchbaseLite-Enterprise") {
version = "~> 2.8.1"
}
}
...
}
...
I get a different error if I use the non-enterprise release. Same build.gradle.kts except with pod("CouchbaseLite"). I get the error:
Exception in thread "main" java.lang.IllegalArgumentException: 'CBLQueryMeta' is going to be declared twice

Both these pod specs compile without problem in an Xcode project. But Kotlin native seems to run into issues with them.
Update:
The pod("CouchbaseLite") error seems to be caused by having both a CBLQueryMeta and CBLQuery interface defined. There's a YouTrack issue for this. This error will likely still be a problem with CouchbaseLite-Enterprise, if the original error could be resolved.
Update 2:
If I remove the { version = "~> 2.8.1" } or put it in the function call directly pod("CouchbaseLite-Enterprise", "~> 2.8.1") I get a different error:
Exception in thread "main" java.lang.Error: /var/folders/pv/3_5xn0dd0v5bf6sxbfcsq_wr0000gn/T/6649487835163649080.m:1:9: fatal error: module 'CouchbaseLite_Enterprise' not found

Update 3:
I filed a YouTrack issue for this. It seems this might have something to do with the dash - in the CocoaPod library name. There was an issue that's been closed that had a fix for this by changing the module name to replace the dash - with an underscore _, but the fix doesn't seem to be working.
