Hello everyone! It’s possible that I’m doing something wrong, but I’d like to ask if, when you delete Derived Data or Build Folders in Xcode, you are then able to compile the project correctly and import the “shared” framework without errors in the iOS project. At the moment, I’ve been encountering several errors because it says it can’t find the “shared” framework, which actually makes sense to me. However, I thought that dependencies (including the “shared” framework) would be compiled first to avoid these resolution errors. This forces me to comment out all the imports to be able to build. Once the build is done, everything returns to normal. I’d like to avoid this use-case because it’s a bad developer experience 😅. Fortunately, on the iOS app side, I have all the code abstracted and use DI, so I end up only commenting out a few files in my “data package.” Is this happening only to me? Is there a configuration I’m getting wrong?
I’ve external spm dependencies and local spm dependencies, only the regular framework seems to “break”.

cd "$SRCROOT/.."
./gradlew :shared:embedAndSignAppleFrameworkForXcode

This is the first setting on Build Phases, looks ok to me 🤷‍♂️

I’ve also encountered this issue. In my case, I made several configurations (DebugDev, ReleaseDev, DebugStg, …) and it was building but it ends up not being accessible to xcode. I changed the configuration back to Debug and Release and things ran smoothly from there on my end. This might be specific to my case so check your build settings and check if it’s building on the kotlin side too.

Thanks! Will take a look

[Guilherme Delgado]

@Rick Clephas I’ve studied the KT-59751 but in my case I do not have any Xcode configurations besides the “default”:
Created by Android Studio

cd "$SRCROOT/.."
./gradlew :shared:embedAndSignAppleFrameworkForXcode

Created by Kotlin Wizard

if [ "YES" = "$OVERRIDE_KOTLIN_BUILD_IDE_SUPPORTED" ]; then
  echo "Skipping Gradle build task invocation due to OVERRIDE_KOTLIN_BUILD_IDE_SUPPORTED environment variable set to \"YES\""
  exit 0
fi
cd "$SRCROOT/.."
./gradlew :shared:embedAndSignAppleFrameworkForXcode

It always fails no matter which I use.

I don’t know how to fix this 🤔

[Rick Clephas]

Hmm and does it make a difference if you both clear the Xcode and Gradle caches instead of just the Xcode caches?
Could you share the build logs from Xcode, specifically those of the Kotlin build script step?

[Guilherme Delgado]

I’ve deleted .gradle/cache/ content, cleaned the project on Android Studio and also the iOS Derived Data. Then I’ve built the project in Android Studio with sucess. Next on Xcode I’ve tried the same but it failed:

[Guilherme Delgado]

DomainProtocols import SharedSDK (shared framework) so it will fail with
> No such module ‘SharedSDK’

[Guilherme Delgado]

now to work I’ve to comment all theses imports and build. 😞

[Rick Clephas]

Hmm it looks like the Kotlin build script isn’t being run yet. Is the Kotlin build script configured for your DataExtensions target?

[Guilherme Delgado]

I only have one target and it’s the “MainApp” target 🤔

[Guilherme Delgado]

could this be the problem?

[Guilherme Delgado]

This target on the General tab has all this framework dependencies added

[Rick Clephas]

Based on the error message the DataExtensions target imports the DomainProtocols module, which I am guessing is your Kotlin module?

[Guilherme Delgado]

oh no no DomainProtocols is another local spm

[Guilherme Delgado]

I have only one import from Kotlin it’s the SharedSDK

[Rick Clephas]

Oh, in that case could it be that DomainProtocols also fails to build? Resulting in the no such module error?

[Guilherme Delgado]

(but DomainProtocols imports SharedSDK)

[Rick Clephas]

Normally you would need to add the Kotlin build script to the target that is using the shared Kotlin module.
But I am not sure how that would be done with a SPM package

[Guilherme Delgado]

(must I specify something in their Package.swift regarding shared kotlin lib?)

[Rick Clephas]

Not 100% sure, but I believe there is no way to specify a custom build script action for a SPM package

[Guilherme Delgado]

yeah, I’ve tried to search about it and didn’t find anything about it

[Guilherme Delgado]

Is it possible to force this script to run before the spm dependencies?

[Guilherme Delgado]

maybe here?

[Rick Clephas]

Yeah but it seems that SPM dependencies are being build before that script is run

[Guilherme Delgado]

I also think that’s the case

[Guilherme Delgado]

because when I comment > run > uncomment: it’s ready

[Guilherme Delgado]

so I would say that spm won’t take shared lib into account, then the script runs, then I uncomment, but the lib is cached and created, so spm will be able to see it 🤔

[Guilherme Delgado]

what if I created a dummy spm with the same name 😅 but empty, would it work?

[Rick Clephas]

Correct. I think this is more of an SPM limitation.

[Rick Clephas]

In order for it to work you would need to remove any references to the shared Kotlin module from any SPM dependencies. Including references to SPM dependencies that were removed

[Rick Clephas]

But that probably won’t work automatically

[Rick Clephas]

I am not sure what the order of dependency building is, but if it first builds other Xcode targets then you could add a dummy Xcode target with the Kotlin build script

[Guilherme Delgado]

that’s a good idea, I’ll try it 😉

[Guilherme Delgado]

I found a solution (or a partial)

[Guilherme Delgado]

we can add build scripts for any action of the Scheme

[Guilherme Delgado]

so I’ve added the same script in the Build pre phase, and know the SharedSDK is found and built before 🙂

[Guilherme Delgado]

but for some reason now, one of the SPM are failing. Still looking into it, but maybe am in the right path 🙏

it worked 😎

Thanks for the help 🙌
