I have a project set up following https://kotlinlang.org/docs/native-cocoapods.html#add-and-configure-kotlin-cocoapods-gradle-plugin that worked fine last week, but now when I build, the ‘shared’ framework in the cocoapods folder only has a header file named ‘placeholder.h’ with nothing useful in it. My app won’t compile anymore, since XCode can’t find any of the classes in my KMM library.

I have a project with two modules that both use cocoapods. They both depend on the Intercom pod and are set up nearly identically. One of them builds just fine, but the other always fails when commonizing the cinterop for Intercom with this message

Unresolved classifier: cocoapods/Intercom/ICMHelpCenterCollectionContent

What should I be looking for to figure out why this fails for only one of the modules?

> Task :iosX64Test
Invalid device: iPhone 12
java.lang.IllegalStateException: command '/usr/bin/xcrun' exited with errors (exit code: 148)

Yeah I don’t have an iPhone 12 simulator, but why does it try running my tests on it? There are other simulators available, why does it want to use something that isn’t there?

Hello guys, I am working in Kmm library. I am in iOS part and using cocoapods as dependency manager. I am new in ios and kmm. I am reading the cocoapods doc in kotlin. I am adding my gradle code in the thread. I am understand that my cocoapod code is generating .podspec file. But there is no instructions given in doc to generate framework. I want to use pod private spec, but I don't understand what I need to share in the repo. Can someone help me how can I generate framework and what files I can share in private pod sec repo. Any working examples will be great. Thanks

[Solved] In the past few days, I’ve noticed that when I build an iOS binary, I’m getting a failure at linkDebugFrameworkIosArm64. More details in 🧵

Is there a way to cause compilation to fail if the deployment target is iOS 12 and the Kotlin native code references a class or method from a later os version? I have tried this with no success, code compiles and the app crashes on launch.

The docs say that

suspend

functions are available as functions with callbacks and

async

functions in swift. Unfortunately this means that interfaces with

suspend

functions in Kotlin are exported as protocols with both

async

and callback requirements in Swift. And

async

is not supported for iOS 12 🙃 Is it possible to generate only the callback definitions?

quick question: Is HealthKit class

HKVerifiableClinicalRecordQuery

supported? I can’t seem to access it through Kotlin. Thank you.

How do you get rid of these errors? Happens every time I update XCode in a project with a Kotlin cocoapods dependency.

I updated to Kotlin 1.7.0 and now the cocoapods plugin tries to build a dependency for armv7 for some reason, why? That dependency doesn’t support armv7.

Hi guys, I’m having trouble doing a

switch

statement with Kotlin/Native enums in Objective-C. I’m getting the error

Statement requires expression of integer type ('NtvCoreRateType *' invalid)

. It seems that Kotlin enum classes don’t get converted into proper enums in objective-C, so I’m wondering if its at all possible to do a switch statement with them? And if not, what is the expected way to compare them?

Hello good people. I am looking for some ways to publish a KMM library for iOS without sharing the source code. Any tips or ideas are very welcome.

I am working on a KMM library that is distributed as an xcframework for iOS and have an Objective-C dynamic framework that I depend on using cinterop currently. I created a def file that defines linker flags to link against the Obj-C framework. When I integrate this into my app (also KMM), I can use gradle’s implementation(project), but I still have to manually embed the frameworks into the app using XCode. Is there a way to have KMM embed the Obj-C frameworks with my KMM framework so I don’t have to embed them in the final app in XCode?

I have a need to expose a newer Swift-only API to Kotlin Multiplatform. I understand I will need to write an Objective-C wrapper to re-expose it via ObjC ABI. Can anyone share experience to say if this has been straightforward for them? Any pitfalls or tips with project setup? Thanks!

Halo guys any have experience kmm on iOS ?

Could you share the experienced?

I'm trying to understand how the cocoapods plugin works to work around this issue https://youtrack.jetbrains.com/issue/KT-53127/Breaking-change-in-Cocoapods-plugin-between-Kotlin-1621-and-170 Does anyone know why it tries to build a project with the latest versions of the dependencies you specify instead of the right version? I have this in my Gradle build file:

pod("MaterialComponents/TextFields", "~> 123")

The generated Podfile in build/cocoapods/synthetic/IOS contains this:

pod 'MaterialComponents/TextFields'

Then obviously the Podfile.lock contains:

- MaterialComponents/TextFields (124.2.0)

And the build fails, potentially because this version is broken. Is it a bug? I tried with Kotlin 1.6 and 1.7 and it does not seem different

Anyone have advice for kmm interop with Swift? Specifically how Kotlin

Bool

Int

and

Double

become

KotlinBool

Int32

and

KotlinDouble

It looks like CocoaPods integration is broken in (at least)

1.6.21

and

1.7.10

in case you want to *depend on a Pod that requires the most recent iOS versions (15.4/15.5)*; filed a bug here: 🐛 KT-53174 CocoaPods: Synthetic Podfile does not specify deployment target

Looking in the CocoaPods plugin ("open class CocoaPodsExtension") its copyright date is 2010-2019 ! Does this mean I'm picking up an old version??? If so, how? Why?

Where would I find information on this plugin: id(“org.jetbrains.gradle.apple.applePlugin”)? I don’t see a GitHub repo for it. Is this plugin specific to AppCode? Is it released or in an experimental stage? I saw some info here but that’s all I could find.

Any AppCode users here? How can I update swift version? I found the project settings but its seems to do nothing?

When using the Apple Gradle DSL plugin

org.jetbrains.gradle.apple.applePlugin

, does anyone know how control which destination(s) are being built for? I can query

destinations

in the DSL which tells me Device and Simulator. I need to restrict it to only Device as I have a Project dependency which won't build for Sim. When using

xcodebuild

this is the

-destination

switch... I guess if I can find the source to the Apple plugin I could find if that switch is ever applied and trace it back...

I'm trying to set UIView's accessibilityIdentifier property, but it's not recognized by the Kotlin native compiler for either example 1 or 2 below. Any help in how I might set the accessibilityIdentifier property via Kotlin would help me greatly. I'm happy to add custom OBJ-C bindings, but I would appreciate help being pointed to a tutorial to learn how to do so. Any help would be very appreciated. Example 1:

class MyView: UIView {
    override init(frame: CGRect) {
        super.init(frame: frame)
        self.accessibilityIdentifier = "my-custom-view"
    }
}

Example 2:

val view: UILabel = ...
view.accessibilityIdentifier = "my-custom-view"

I’m curious. Anyone who ever asked or tried to add some sort of curl logger for Ktor in iOS Native? Thanks.

Has anyone successfully gotten the gradle based iOS projects via

org.jetbrains.gradle.apple.applePlugin

working, and maybe more specifically on an m1 device?

Has anyone figured out a nice way to bridge a

State

from

StateFlow<State>

to SwiftUi as

@ObservedObject

? Rather than doing

@Published var state: State = State.companion.DEFAULT

viewModel.onState { (state) in
  self.state = state
}
