Does anyone have an issue finding the iosMain source set I a

Question

Does anyone have an issue finding the iosMain source set I added the following code to my `build gradle kts` ``` sourceSets iosMain dependencies implementation io ktor ktor client ios $ktorVersion ``` But Gradle complains with KotlinSourceSet with name iosMain not found

Artyom Degtyarev [JB] · Answer

Please make sure that you have a target with name ios Default source sets name depends on the target name as described here <https kotlinlang org docs reference building mpp with gradle html default project layout>

Ohhhh

By introducing my code to generate a fat framework I changed the architecture name to `iosArm64` and therefore the target name Does this mean I ll now have to add the dependencies to both the `iosArm64` as well as the `iosX64` targets

Sam · Answer

You could filter the list of sourceSets by ones starting with ios and then calling dependencies on each one

Nice it works now Thank you so much < Artyom Degtyarev JB > tada

Marc Reichelt · Answer

< Sam> yep that does make sense as well And the Kotlin DSL makes this damn nice to read

Marc Reichelt · Answer

Now I just need to figure out how to define that those 2 targets actually have the same source set `iosMain` otherwise I would have to have 2 source directories `iosX64Main` and `iosArm64Main` with the same content

Maybe these threads can help please take a look

Marc Reichelt · Answer

Thanks that looks useful I will dig my head around this but this is definitely something where we will loose many new developers jumping on KMP because it s just pretty complex and usually people would like to concentrate on the business stuff and not on figuring out how to resolve all those Gradle configuration stuff

Oh wow there are so many things that are new in the native multiplatform world Like the fact that there is no `runBlocking` for coroutines on iOS so now I have to figure out how to do this myself If the method is called on a non UI thread how can I simply make ktor client make a HTTP request on the thread it s currently called

Sam · Answer

Ktor calls have to be done on the main thread currently It has some `object` types that are initialized there on startup If a call is made on a background thread it will access those objects and cause an illegal state exception

Marc Reichelt · Answer

awww damn

Marc Reichelt · Answer

that s pretty much a dealbreaker confused

Sam · Answer

The call doesn t block and on iOS it is using NSURLSession which actually makes the call on a background thread You would want to avoid doing any heavy workloads with the result on the main thread For that you could use workers

russhwolf · Answer

There is runBlocking for iOS It s just missing from JS so it s not in the common stdlib But you can define your own expect actual alias if you just care about JVM and Native

Marc Reichelt · Answer

Wow that s pretty cool defining an `expect` runBlocking method with the same syntax as the real ones works
