Kotlin Coroutines - How to block to await/join all jobs?

Question

I am new to Kotlin/Coroutines, so hopefully I am just missing something/don\'t fully understand how to structure my code for the problem I am trying to solve.

Runblocking should mean you don't have to call join. Launching a coroutine from inside a runblocking scope should do this for you. Have you tried just:

fun processData(lstInputs: List): List {

val lstOfReturnData = mutableListOf()

runBlocking {
    lstInputs.forEach {
            launch(Dispatchers.IO) {
                lstOfReturnData.add(networkCallToGetData(it))
            }
   } 
}

return lstofReturnData
