kotlinlang

I am working (together witg gemini from google) a kmp app. we arte trying to remove an element from a mutablelist. according to the kotln documentation `val removed = _bloodPressureRecords.removeIf { it.id == id }` should work, but accroding to intellij, removeIf does not exist kotlin = "2.1.21", kotlinx-coroutines = "1.10.2", ktor = "3.1.3"

A short code snippet might help. Are you certain the list is mutable at that point?

```private val _bloodPressureRecords = mutableStateListOf&lt;BloodPressureRecord&gt;()
    val bloodPressureRecords: List&lt;BloodPressureRecord&gt; = _bloodPressureRecords

...
return try {
            val response: HttpResponse = apiClient.delete("$BASE_URL/bloodpressure/$id")
            if (response.status == HttpStatusCode.NoContent || response.status == HttpStatusCode.OK) {
                // Successfully deleted on server, now remove from local list
                val removed = _bloodPressureRecords.removeIf { it.id == id }```

Its a mutableStateListOf, which has type SnapshotStateList.

thanks, I should have checked that, using `removeAll {it.id == id}`
