Question

So maybe this is asked here already but we have an issue All functions in our shared code marked as ```suspend``` do not show up in the compiled iOS code and cannot be called Do we have to remove coroutine support from our shared code or is there some trick to make it work

kpgalligan · Answer

iOS has no concept of suspend You need to pass a callback

Juhani Lehtimäki · Answer

This confuses me a bit as there is a KMP library for coroutines and no compilation errors The functions just are missing

Juhani Lehtimäki · Answer

ktor also uses coroutines to make calls

Juhani Lehtimäki · Answer

is there a nice pattern to implement a multi platform API that calls backend with ktor

Juhani Lehtimäki · Answer

but doesn t use suspend in the interface

kpgalligan · Answer

You can t expose suspend methods to the iOS header We just have the external method take a lambda and have Swift pass that in

Juhani Lehtimäki · Answer

ok

Juhani Lehtimäki · Answer

but you can t use launch in KMP either as far as I figured out or

kpgalligan · Answer

On phone right now but can dig up a sample in a bit

Juhani Lehtimäki · Answer

so how can I call Ktor

Juhani Lehtimäki · Answer

cool thanks slightly smiling face

kpgalligan · Answer

Why can t you use launch

Juhani Lehtimäki · Answer

does not compile confused

Juhani Lehtimäki · Answer

sigh Maybe somethign is missing

Larten · Answer

You can use launch and works

Juhani Lehtimäki · Answer

okay must be gradle messed up then thanks I ll dig into it

Olenyov Kirill · Answer

Also there are solutions to generate callbacks

Juhani Lehtimäki · Answer

oh that s cool Thanks

kpgalligan · Answer

Interesting Never heard of these

Juhani Lehtimäki · Answer

These both look a bit old Are they still active

kpgalligan · Answer

They re def old Digging a bit

Juhani Lehtimäki · Answer

We had an issue with older libraries that they don t compile anymore as they were compiled by older Kotlin verison

Juhani Lehtimäki · Answer

as an idea these look amazing

Juhani Lehtimäki · Answer

especially ``` Recast```

kpgalligan · Answer

Native libraries need to be updated There look like compiler plugins although that seems like a strange risky place to be just now

kpgalligan · Answer

Got it For recast you need to use kapt to make source for iOS

Juhani Lehtimäki · Answer

do you feel it s a worth a try at this stage

kpgalligan · Answer

The other one uses <https github com Foso MpApt> which I ve avoided but see how it goes

kpgalligan · Answer

Not even close

kpgalligan · Answer

But that s me

Juhani Lehtimäki · Answer

I m a complete n00b stumblin in dark trying to get our lib working so I happily take in your input

kpgalligan · Answer

I don t find the callback scheme to be that difficult to implement and I d expect to spend more time on sorting out config

Juhani Lehtimäki · Answer

I ll just write a wrapper into the repository that calls the suspend ones and responds in callbacks

kpgalligan · Answer

Yeah it s extra code but not that hard to do

Juhani Lehtimäki · Answer

yeah exactly And if something breaks at least I know I did it smile

kpgalligan · Answer

I was going to send a sample but then updated intellij then got distracted

Juhani Lehtimäki · Answer

Thanks Much appreciate the expertise slightly smiling face

kpgalligan · Answer

What s your github I ll add you to our new sample app

Juhani Lehtimäki · Answer

JuhaniLehtimaeki

Juhani Lehtimäki · Answer

thanks slightly smiling face

ribesg · Answer

My solution is to not write any Swift code stuck out tongue

kpgalligan · Answer

Added but forgot we re using Flow not passing in callbacks to methods

kpgalligan · Answer

Droidcon app has more examples although we re super overdue for an update <https github com touchlab DroidconKotlin blob kpg mt coroutines sessionize lib src commonMain kotlin co touchlab sessionize AboutModel kt L14>
