Hi everyone, I am having issues with Objective-C interop in Kotlin

[Sean Chin Jun Kai]

I have the following swift code:

@objc public enum FirebaseAIErrorObjc: Int {
case server = 0
case promptBlocked = 1
case responseStopped = 2
case serialization = 3
case invalidAPIKey = 4
case quotaExceeded = 5
case unsupportedUserLocation = 6
case serviceDisabled = 7
case contentBlocked = 8
}


I import it into my kmp code as such:

cocoapods {
    ios.deploymentTarget = libs.versions.ios.deploymentTarget.get()
    framework {
        baseName = "FirebaseAI" // Not FirebaseAIBridge due to ld: can't link a dylib with itself. same install_name as dylib being built
    }
    pod("FirebaseAIBridge") {
        source = git("<https://github.com/SeanChinJunKai/FirebaseAIBridge|https://github.com/SeanChinJunKai/FirebaseAIBridge>") {
            branch = "main"
        }
        extraOpts += listOf("-compiler-option", "-fmodules")
    }
}

But FirebaseAIErrorObjc is unresolved

[Sean Chin Jun Kai]

I have another enum from previous commits that gets resolved

@objc public enum ContentModalityObjc: Int {
case unspecified = 0
case text = 1
case image = 2
case video = 3
case audio = 4
case document = 5

public static func from(_ modality: ContentModality) -> ContentModalityObjc {
switch modality.rawValue {
case ContentModality.text.rawValue:
return .text
case ContentModality.image.rawValue:
return .image
case ContentModality.video.rawValue:
return .video
case ContentModality.audio.rawValue:
return .audio
case ContentModality.document.rawValue:
return .document
default:
return .unspecified
}
}
}

It shows up in build/cocoapods folder but im not sure why I cannot import it into iosMain

[François]

Hi, it’s not the cocoapods source that is important, it’s the generated cinterop file (.knm) who is!
look inside
build/classes/kotlin/commonizer/..._x64)/fr.frankois944_library-cinterop-appleDeps/default/linkdata

[François]

did you try the spm way ?

[Sean Chin Jun Kai]

@François its not inside either. It is working with another enum of same format tho

[François]

try a full clean build or disable the gradle cache

[Sean Chin Jun Kai]

btw thanks for introducing ur spm library, i might use it to distriubte using spm too but not for now

[Sean Chin Jun Kai]

how can i disable the gradle cache? Is it

kotlin.native.cacheKind.iosSimulatorArm64=none
kotlin.native.cacheKind.iosArm64=none

[François]

yes and also

org.gradle.caching=true -> false
org.gradle.configuration-cache=true -> false

[Sean Chin Jun Kai]

thank you ill try it out

[Sean Chin Jun Kai]

im really hoping for direct swift interop with kotlin

[Sean Chin Jun Kai]

now it doesnt work again lmao

[François]

I gave up on cocoapods; I can’t help you much about using custom pods.

[François]

maybe you should use a local one instead of remote one during your devs

[Sean Chin Jun Kai]

Hi @Andrey Yastrebov, could you please take a look at this? The swift code is inside this repo: https://github.com/SeanChinJunKai/FirebaseAIBridge

[Andrey Yastrebov]

take a look at this

What exactly do you want me to look at?

[Sean Chin Jun Kai]

It’s the FirebaseAIError.swift file

[Sean Chin Jun Kai]

i’m pretty sure the declaration is correct but i’m not sure why it won’t show up in iosMain

[Sean Chin Jun Kai]

however adding new swift classes with @objc notation does show up in iosMain

[Sean Chin Jun Kai]

you can ignore it

[Sean Chin Jun Kai]

i got it to work
