How to set multiplatform flavor based on XCode target with CocoaPods?

[mr-kew]

I used to use script build phase for this on kotlin version 1.19.20 and BuildKonfig version 1.5.0 and it worked fine:

if [ $ENABLE_PREVIEWS = "YES" ]; then exit 0; fi
cd "$SRCROOT/.." && ./gradlew :shared:embedAndSignAppleFrameworkForXcode -P buildkonfig.flavor=prod

It is somewhat inspired by the futured template

But since updating to kotlin to version 2.0.0 and BuildKonfig version 1.5.1, it does not compile and says:

'embedAndSign' task can not be used in a project with dependencies to pods.

I tried switching to any other task like build, assemble or generateBuildKonfig, and moving the build phase up and down the list. It compiles & runs, but the flavor is not set.

Upon reverting back to original versions it turns out that the flavor is also not set when using other tasks instead of embedAndSignAppleFrameworkForXcode.

So the question is:

What other task can I use to set the multiplatform flavor from XCode target's build phases instead since the embedAndSignAppleFrameworkForXcode is now prohibited for CocoaPods?

Ok, so I finally figured it out.

Running embedAndSign task in a CocoaPods project to set a gradle.property is wrong. As discussed in the original issue, it can lead to linking issues and generally does not make much sense, as the shared module is already build as a pod.

Intended way (as I understand it):

1. Edit iOS configurations to contain the flavor name (e.g. ProdDebug). It can be done in project settings under the Info tab. CocoaPods should then automatically create corresponding configuration files under the Pods folder.

2. Edit your scheme for each target to run the corresponding configuration.

3. The configuration name is then automatically passed to the gradle when building the module inside the shared.podspec:

"$REPO_ROOT/../gradlew" -p "$REPO_ROOT" $KOTLIN_PROJECT_PATH:syncFramework \
    -Pkotlin.native.cocoapods.platform=$PLATFORM_NAME \
    -Pkotlin.native.cocoapods.archs="$ARCHS" \
    -Pkotlin.native.cocoapods.configuration="$CONFIGURATION"

4. Map new iOS configurations to corresponding NativeBuildTypes:

xcodeConfigurationToNativeBuildType["FlavorDebug"] = NativeBuildType.DEBUG
xcodeConfigurationToNativeBuildType["FlavorRelease"] = NativeBuildType.RELEASE

5. Access the configuration name:

val configuration = findProperty(KotlinCocoapodsPlugin.CONFIGURATION_PROPERTY)

6. Extract the flavor from it and set the multiplatform flavor before the generateBuildKonfig task, using afterEvaluate block for example:

afterEvaluate {
    setProperty("buildkonfig.flavor", flavor)
}

Wait... You lost me at 5. =) You wouldn't happen have a small sample project with this set up, would you?

[mr-kew]

@Qw4z1 Sadly no. But you should do 5 inside the afterEvaluate block. It should return String containing name of your configuration.
