Hi, I have problems getting DefaultComponentContext(...) on iOS:
+ I am using cocoapods
+ in commonMain:

api(libs.decompose)
api(libs.essenty.lifecycle)

+ in cocoapods:

export(libs.decompose)
 export(libs.essenty.lifecycle)
 transitiveExport = false
 isStatic = true

+ in iOSApp.swift

DefaultComponentContext(lifecycle: lifecycle)

=> cannot find 'DefaultComponentContext' in scope
Any idea?

This looks similar to another question that was asked on GitHub. I never used cocoapods, maybe someone here could help? At the moment this looks like a generic KMP problem, Decompose library shouldn't be different from any other library in this regard. Maybe worth asking in #multiplatform.

[Jan]

ok, I will keep trying and let you know If I resolved that issue. Will update githup as well.

[Jan]

yes, I can confirm its breaking if I add this to commonMain:

// Version Decompose: 2.0.0-alpha-02
// Version Decompose-Extensions: 2.0.0-compose-experimental-alpha-01
// Module: com.arkivanov.decompose:extensions-compose-jetbrains
implementation(libs.decompose.extensions.jetbrains)

[Arkadii Ivanov]

Can you try using the same version across all decompose modules? Either normal one or experimental.

[Jan]

hm ...

Could not resolve all dependencies for configuration ':gs_api_multiplatform:iosArm64CompileKlibraries'.
   > Could not resolve com.arkivanov.decompose:extensions-compose-jetbrains:2.0.0-alpha-02.

[Jan]

ok, have to go now. Will have a look tomorrow again ... thanks for help

[Arkadii Ivanov]

If you need compose for iOS, then please use the experimental version for everything.

Hello, good day folks. I reported issue on the Github link shared. I have tried downgrading library and kotlin versions, tried different combinations, but they all produce some new error and didn't work. May be because Ia m using AS Flamingo. Therefore I reverted back to latest update, and facing same issue again.

In the source code, I can see DefaultComponentContext inside DefaultComponentContextBuilderKt. Also, it is declared as a class in DefaultComponentContext. I am not a KMM pro, just thinking why all the classed declared in here are not accessible from xcode. Is it because of kotlin 1.8.20, KMM's cocoapods support or anything else? Is there something we can do to debug? I really wanted to use this library 🌟

[Anum Amin]

The last resort I can think of is to disintegrate cocoapods and try with regular. But I really don't know if it's cocoapod support issue from KMM

[Arkadii Ivanov]

Maybe try asking in #multiplatform channel?

[Arkadii Ivanov]

Also please make sure you are using the same version for every Decompose dependency (e.g. decompose and extensions-compose-jetbrains must have the same version)

[Anum Amin]

yes, it's same.

api("com.arkivanov.decompose:decompose:2.0.0-alpha-02")
api("com.arkivanov.decompose:extensions-compose-jetbrains:2.0.0-compose-experimental-alpha-02")
api("com.arkivanov.essenty:lifecycle:1.1.0")

[Anum Amin]

I have posted on the channel. Lets see if we get any response

[Arkadii Ivanov]

But it's not the same, you have to use the experimental version for both

[Anum Amin]

I replaced experimental for both decompose and jetbrain extension, but still the same. Also only following are accessible:

[Arkadii Ivanov]

It feels that only things actually used in Kotlin are exported, isn't it?

[Jan]

Is iosApp build successfull via xcode/androidStudio? If not, make it build by uncomment all broken stuff and try to build until its successful. Maybe the iOS framework is still the old one …

I would say yes majority are those classes. StackNavigation is not accessible although I have used it in root component.

I am aware of this fact. I have commented out my all code and trying with limited lines only. Without DefaultComponentContext, it compiles fine. Did you try at your end with same versions?

[Arkadii Ivanov]

Would it be possible to share a reproducer?

[Anum Amin]

Sure, I can prepare a sample project. Will let you know

[Arkadii Ivanov]

Maybe, as an experiment, try also exporting the following?

essenty-lifecycle = { group = "com.arkivanov.essenty", name = "lifecycle", version.ref = "essenty" }
essenty-stateKeeper = { group = "com.arkivanov.essenty", name = "state-keeper", version.ref = "essenty" }
essenty-instanceKeeper = { group = "com.arkivanov.essenty", name = "instance-keeper", version.ref = "essenty" }
essenty-backHandler = { group = "com.arkivanov.essenty", name = "back-handler", version.ref = "essenty" }

[Anum Amin]

It's working 😄 😄 🎉🎉 I can see the classes accessible in the xcode now. Thank you @Arkadii Ivanov for your time and help! ❤️

[Arkadii Ivanov]

This still looks like a bug, perhaps in Cocoapods plugin!

[Arkadii Ivanov]

I will ask someone from JB.

[Arkadii Ivanov]

Could you please also share what Essenty version you are using?

[Anum Amin]

I see. I am using 1.1.0 Essenty version. Do you still need the demo to reproduce the issue?

[Arkadii Ivanov]

No need for now, thanks!
