Hello folks,

xcode-kotlin info

show null with Xcode16.2, is there a problem? Thx.

Hi, we're using SQLiter and SKIE and are facing some linker issues. I think I understand the cause, but I'm not sure how to address this and I wonder if someone here might have ideas. For context, our setup is basically this: 1. We have a KMP library depending on SQLiter to access SQLite. 2. I don't think this is relevant to this issue, but we're linking sqlite3 statically because we need extension loading which is otherwise not available on macOS. We create a

<http://libsqlite3.ar|libsqlite3.ar>

by invoking clang through the KMP

PlatformManager

and we include that with a cinterops definition having a

staticLibraries

option. 3. We then export our project as an xcframework. I know that our setup generally works because Kotlin tests depending on SQLite pass on all platforms we care about (and I checked with

nm

that a copy of SQLite is part of the test executable there). When consuming the exported xcframework on a Swift project on macOS though, we get linker errors about missing symbols like

sqlite3_column_database_name

or

sqlite3_win32_set_directory

. What all the missing symbols have in common is that they're optional or platform-specific, so they're not enabled by default (

column_database_name

needs

SQLITE_ENABLE_COLUMN_METADATA

, for example). From my understanding, the root cause is this: 1. The cinterop setup on SQLiter creates Kotlin functions for all symbols defined in

sqlite3.h

. 2. When we test with Kotlin, we compile an executable from which unused symbols are removed by the linker (?), and since we're not calling

sqlite3_column_database_name

anywhere, the undefined symbol is never part of the executable. 3. When exporting the library as a framework, the symbols aren't stripped and consumers can't link our framework? Is there a way for us to fix this by e.g. removing unused symbols when creating the xcframework?

Hello y'all. I'm working on scaling up KMP in my current project. It's moderately large with dozens of developers. Our kmp "library" has a large number of modules. We use the library model with a swift package and maven distribution for consuming the library. Local development is done pretty awkwardly with by publishing a Swift package locally on iOS and a local maven for android. I'm sold on this blog posts about compiling from source: https://touchlab.co/kmp-teams-use-source Hopefully we'll soon be compiling from source on iOS soon when doing local development, but I feel like a better integration between our gits is needed. A tighter linking between the 3 gits and building from source by default. I think a monorepo is out of the question due to team/project size. Basically I want submodules, but good. :) Is anyone here using GitPortal with success? Or a homegrown approach that works in a similar way?

Is there a version of SKIE that works with Kotlin 2.1.20?

Hi everyone. I am finally getting around to updating my KmmBridge setup to 1.2.1 (from 0.5.5) , and I'm running into a problem. I have a custom Gradle plugin that is applying configuration for my umbrella (allShared) module. With 0.5.5, I could call the

addGithubPackagesRepository()

method from my plugin, like this:

class UmbrellaModuleConventionPlugin: Plugin<Project> {
    override fun apply(target: Project) = with(target) {
        with(pluginManager) {
            apply(kmpLibs.plugin("touchlab.kmmbridge"))
            apply(kmpLibs.plugin("kotlin.cocoapods"))
        }
        extensions.configure<KotlinMultiplatformExtension>(::configureCocoapods)
        addGithubPackagesRepository()

        ...
    }
}

But when I update to 1.2.1, I now get an error:

Unresolved reference: addGithubPackagesRepository

The line above that applies the kmmbridge plugin

apply(kmpLibs.plugin("touchlab.kmmbridge"))

is using the "github" version of the plugin:

touchlab-kmmbridge = { id="co.touchlab.kmmbridge.github", version.ref="touchlab-kmmBridge"}

And the gradle config for my plugin module, is using the kmmbridge gradle plugin:

dependencies {
    compileOnly(kmpLibs.android.gradlePlugin)
    compileOnly(kmpLibs.kotlin.gradlePlugin)
    compileOnly(kmpLibs.touchlab.kmmbridge.gradlePlugin)
}

touchlab-kmmbridge-gradlePlugin = { group="co.touchlab.kmmbridge", name="kmmbridge", version.ref= "touchlab-kmmBridge" }

I'm not sure where I'm going wrong???

This article talks about importing the .wasm file in the HTML and then accessing it from the window object. How do I go about if I want to use Wasm in React which doesn't have any HTML file and all are .js files?

Circling back/extending a previous conversation ... My teams have been using KmmBridge to share our KMP code as a library for our android and ios apps. We have a development process setup that mostly works well for us. There's one piece that I wish we could do better, but I'm not sure how/what to do ... When working on a feature for our apps, a dev team might make several commits to a feature branch in the KMP repo. For the devs, this is no problem. We use the Local Dev Flow . They have the appropriate feature branch checked out, and can do their dev on the feature. The issue is with our automated builds for our QA process. We use Github Actions to do a build of the app when a PR is merged to a feature branch. When that happens, the app needs to know what "version" of the kmp library to use. To this point, we've just been publishing a new version with every piece of work on the feature so that there's a new version number for the automated build to pull. But that's really not a great solution long term. We're publishing tons of versions, many of them with "partially working" features. We may want to expose the published library to some third party partners, and at that point we definitely don't want to expose "half baked" versions. I've been trying to think of a way to get those automated feature builds of the apps to work without having to publish a new version of the kmp library. Curious if anyone else has run into and solved this issue?

Hi all, I use KMMBridge to consume my kotlin modules in ios code , I am currently the only developer in my team, so I don't have any pipeline setup , I. use

/.gradlew spmDevBuild

to make the framework and then archive my ios project directly through xcode , I was just wondering is there any way here to make the release version of the framework as AFAIK, this produces a debug version of the Kotlin code.

👋, I came across this TouchLab article Beware of Build Time Bloat due to having very, very slow CI performance when running iOS tests; it takes about 40+ minutes to complete. I've tried asking around in other channels, such as "multiplatform". Are there any tips in improving CI build times? FYI, this is a multi module CMP project, if we run it locally it's under 10-12 mins but ci it's way longer

Hi everyone! I’m checking how we can use gradle cache to build our KMP multimodule project on CI faster and I see messages like this:

Caching disabled for task ':common:publishKotlinMultiplatformPublicationToGitHubPackagesRepository' because:
  Not worth caching
Task ':common:publishKotlinMultiplatformPublicationToGitHubPackagesRepository' is not up-to-date because:
  Task has not declared any outputs despite executing actions.

Can share with me what should be the reasonable gradle cache configuration for a KMP project?

Hi! Is it possible to create Skie flows from Swift? My use-case is that I have an interface in KMP that uses

Flow<Int>

as the type for one of the fields, and that interface when translated to Swift uses

SkieSwiftFlow<Int>

. This interface should be implemented by one of my Swift classes. What’s the best/easiest way for the Swift class to create an instance of

SkieSwiftFlow<Int>

?

Hi any Skie release targeting kotlin 2.1.20 ?

Hi Team 👋 Quick Question - Interface in Kotlin is reference type whereas Protocols in Swift don't have an inherent type classification. How to leverage the protocol like construct using the KMP? For example:

struct HeadlessPaymentOptionsResponse: Codable, Equatable {
    let param2: String
    let param1: String
}

Hi all. I am updating to the latest KmmBridge (from 0.5.5), and I'm getting the dreaded "*Task 'kmmBridgePublish' not found in root project"* error when running a build via CI (Github Actions). First, yes, I am passing the

ENABLE_PUBLISHING=true

property when running the kmmBridgePublish task. Hoping someone can point me in the right direction .... More details in the 🧵

New kmmBridge question ... Recent versions (1.2.1) publish the xcframework artifact to the github release and reference the URL for that artifact in the Package.swift file that gets produced. In my case, I also need to support cocoapods (bleh ... at least for the time being). The cocoapods quickstart looks like it is configured to still use maven repo (github packages) for the artifact. Is there a way to get it to use the same artifact that spm uses (the file uploaded to the github release)? I was hoping that it would "just work" by using the

gitHubReleaseArtifacts()

configuration, but alas it doesn't seem to. I have the proper deploy keys, netrc entries, etc setup. But my (CI) build fails when validating the produced podspec. I get:

- ERROR | [iOS] unknown: Encountered an unknown error ([!] /usr/bin/curl -f -L -o /var/folders/w5/_8wgjw3j5cg6mgrth3s2kg9m0000gn/T/d20250515-12410-9mp3pi/file.zip <https://api.github.com/repos/myorg/myrepo/releases/assets/255030196.zip> --create-dirs --netrc-optional --retry 2 -A 'CocoaPods/1.16.2 cocoapods-downloader/2.1' -H Accept: application/octet-stream

) during validation.

Perhaps there's something else I need to do with the configuration or ci build workflow?

Following up on my post yesterday about kmmbridge and cocoapods ... Seems like it's a permissions issue when it tries to validate the podspec (and thus pull down the framework from the supplied url). My repo is private, but I have setup an ssh key and a netrc file (the same as what I have been using for kmmbridge 0.5.5), so it seems like it should work, but apparently not. Anyone know of any other authentications I need to provide?

There was a bug with using release builds with cocoapods, but AFAIK, that should be fixed and published. Cocoapods is a huge PITA for CI, and not that many people are using it now, so the KMMBridge config for it rarely gets run or troubleshot. Cocoapods specifically won't publish unless it can build successfully, which means the 15 things you need to do need to be done exactly correct. The only reasonable way to debug that is to try to publish from you local machine with that release URL, then if that works, try to debug why CI is failing.

Hi there! 👋 When might there be a new release of Kermit that includes this recently-merged PR #439?

Hello folks, I have a question that is related to Skie. With Skie adding Swift code to KMP frameworks, this becomes relevant to reduce their final size. I’m curious if anyone has done it already for their framework. I tried to slap something together but the issue I’m facing is this: if I do the stripping after my framework is assembled, this modifies the output of the assembly task, meaning it will be always re-run in the next build, and then stripped again, the cycle continues. What could be a way around that? A broader question: would this make a good configuration option for Skie itself?

given the latest SKIE release, will there be a release for compose-swift-bridge supporting Kotlin 2.1.20 as well? thanks!

I’m in the process of migrating my Android app to KMP, and am about to tackle the sqlcipher/sqldelight part. I noticed this article, but also that it’s about 5 years old. Is it still the way to go, or have there been relevant developments since? https://touchlab.co/multiplatform-encryption-with-sqldelight-and-sqlcipher

I'm having some trouble with KmmBridge. Specifically, the

touchlab/ga-update-release-tag

github action doesn't seem to be working right ... The action runs (successfully), but it doesn't seem to do anything. When I check the tag that gets created in my repo, there is no extra commit, and there is no Package.swift file. However, when I check the github release, the xcframework binary has bee uploaded. That part from the build steps seems to be working. It's just that the update release tag action doesn't seem to be working or doing anything. not sure what I'm doing wrong, or where to start debugging.

I'm using Kotlin Multiplatform resources and SKIE. Is there a way to grab a resource string from Swift code easily? This is just for a default string in an extension on iOS.

I added SKIE to my KMM lib, the diff looks like this: Now I'm getting in Xcode the error "Could not build Objective-c module..." Any idea what the issue might be?

EDIT: resolved, nevermind 🙂 Posting this here, as it seems to be related to suspending functions and enums, apologies if it’s actually more of a general multiplatform question 🙂 Just looking to hear if anyone has experienced something similar We’re having a weird issue where iOS is suddenly not able to see suspending functions and enums. It has worked perfectly fine and just “randomly” broke, even though we hadn’t changed anything major in the latest version of our shared library. It works when building locally with We get errors like

Value of type X has no member Y

where X is a class and Y is a suspending function We also get the error:

No exact matches in global call to onEnum

The only thing we have changed recently is updated to Kotlin 2.1.20, where we got a

Can't find env_blacklist file

error, which was at first fixed by calling

./gradlew commonizeNativeDistribution

before building - that fixed the build and the following released worked just fine. But, now we just made another release and it no longer works on iOS, with the issues mentioned above. On suggestion from KT-72068 we have tried adding

kotlin.native.toolchain.enabled=false

but that made no difference Skie 0.10.2 Kotlin 2.1.20 Gradle 8.11.1 The library is built using assembleFramework and publishing it manually to github package registry

Hey all 👋 I have a question related to

Gitportal

. Library files are added to git, running

gitportal setup library ...

command, even though the library folder is in

.gitignore

. Resulting in:

The following paths are ignored by one of your .gitignore files:
library

Is this an intentional way of force versioning in android/ios repo? We want to use gitportal for our shared code but we'd like to avoid having the same code mixing in PRs etc.

I created a small PR to add wasm support for kermit-koin https://github.com/touchlab/Kermit/pull/447. Thanks cc: @kpgalligan @Sam Hill @Kevin S

After updating to Kotlin 2.2.0 the dreaded linker issue with kermit-crashlytics returned:

dyld[42183]: symbol not found in flat namespace '_FIRCLSExceptionRecordNSException'

This only happens when running tests. I have disabled the native cache, applied the

crashkios

plugin and also added the linker options manually to no avail:

compilerOptions.freeCompilerArgs.addAll(
    "-linker-options",
    "-U _FIRCLSExceptionRecordNSException ",
)

What changed?

A sanity check, using SKIE, if I am publishing a XCFramework using an "umbrella" module which wraps and also publishes other modules, do I need SKIE applied on: • just on the modules that contain the source code • only on the umbrella module • both

I’m setting up Xcode Kotlin and my breakpoints aren’t working. Any tips?
