Finally managed to get a build to TestFlight, thankfully this is far from anything being actually deployed to the App Store. Nonetheless, I needed to do the following: switch Archiving scheme build config type to Debug, set ENABLE_BITCODE as FALSE and finally it worked. This is obviously not the best way to go about things: is there any guide that would explain what kind of a setup a creating a release build for the KMM lib requires?

CONFIGURATION=RELEASE ./gradlew packForXcode

Thanks, I'll give it a go 👍

Alternative use the new assembleXCFramework tasks, which always builds both

[hfhbd]

val xcf = XCFramework()
    iosArm64 {
        binaries {
            framework {
                xcf.add(this)
            }
        }
    }

@hfhbd I’m looking again at making a test build, this time really using a release flavor.

Using something that you suggested, I created a releaseXCFramework with the added gradle task. Now I’m wondering what would be the best way to go about actually making the release archive from XCode: obviously this new XCFramework is not included in the project.

Would you happen to know if there’s a guide somewhere out there on how to do it?

[hfhbd]

There are a lots of guides on kotlinlang.org, eg https://kotlinlang.org/docs/apple-framework.html
https://github.com/Kotlin/kmm-production-sample
and some community samples:

Thanks! I didn't find the official sample somehow! I'll look into these, thanks for taking the time, much obliged 👍 👍

I’ve been researching this once more.

Either I’m just really lost or I cannot seem to find the correct documentation anywhere. Most likely it’s the former 🙂 . In my case I am using CocoaPods.

Anyhow, I can see a few ways to integrate with iOS build:
• Cocoapods: add CocaPods block to KMM module, add Podspec
• Build an XCFramework (or here) and integrate that (also can be done with CocoaPods or manually)
I looked at the above projects:
• kmm-prod-sample does not use CocoaPods, instead Swift packages. It’s using the above Run Script in the Xcode build phases to embedAndSignAppleFrameworkForXcode . I guess this does the trick and that would work nicely for RELEASE build configuration
---> No luck here, as I am using CocoaPods
• Your ComposeTodo app: also does not use CocoaPods. Unfortunately I’m still on Xcode 12 and as such cannot open the project, nonetheless, my guess is that you have a similar setup as above, based on the clients/build.gradle.kts and lack of CocoaPods.
--> No luck here either
• PeopleInSpace uses Cocoapods: Xcode project config actually contains two configs: one for Debug and one for Release : these use different Pods, one of them debug and other release . Here, Podspec doesn’t contain anything that would point to a different Release build. CocoaPods block on the common gradle file is two lines long: I think this one is created with https://github.com/ge-org/multiplatform-swiftpackage but the project also has a Podfile
--> This looks to be the closest example: need to research this multiplatform-swiftpackage a bit more closely, but maybe it could work

[Matti MK]

I was expecting there to be a single given way to do this, but looks like there’s actually quite a few.

Didn’t really expect this part to be so “tricky”, otherwise I’d have put significantly more time into considering the integration in the beginning.

Now I’m already using Podfile in the iOS project to manage dependencies + xcodegen to not have to care about project files.

Google’d around, added this and that to my build gradle: relase build works without any tricks as does the Release archive 🤷

[Matti MK]

Not too confident with this: I’d rather know what’s happening behind the scenes 😅

Xcode build log tells me the following:

So, looks like there’s definitely some release magic happening 🤷
