Can someone help me on my problem? I just transitioned my app from android to compose multiplatform but I keep getting this error when trying to run on IOS `No such module 'ComposeApp'

[Scott Lanoue]

What’s your build.gradle.kts look like for your kmp app? Seems like you’re exporting a different module name than ‘ComposeApp’

Btw this build gradle is located in composeApp/shared

[Scott Lanoue]

Looks good, now what’s the error output?

[Erick]

Error output from running IOS?

[Erick]

This is able to run on android but on IOS it does not work

[Scott Lanoue]

Interesting, seems like you might have to export some of the libraries to iOS but I wouldn’t expect that unless the library calls it out or you’re doing something specific with the library in iOS. What happens if you remove all dependencies and try to build / run?

[Erick]

I just commented out all common dependencies

[Scott Lanoue]

Okay maybe it’s more feasible to do this, could you generate a new KMP project using the wizard, and individually apply your dependencies, then copy your code over? Tedious, but a high likelihood of fixing it rather than us / me trying to debug your setup with limited visibility :)

[Scott Lanoue]

At each step in the process, build and run to make sure it’s working across platforms as expected.

[Erick]

I dont know. Its a big project. I could give it a shot. Do you think it might have to do with setting up IOS when implementing third party libraries. For example with GitLive, I did not follow IOS documentation

This is a step I did not do

cocoapods {
   pod("FirebaseCore") // Repeat for Firebase pods required by your project, e.g FirebaseFirestore for the `firebase-firestore` module.
}

[Scott Lanoue]

Yes that’s exactly what I’m referring to, that matches the errors from your screenshot

[Erick]

Okay I see, I skipped the IOS part for some libraries since I did not have my macbook during a long trip. Im going to try going over the libraries and set it up for IOS before making a new project

[Erick]

Thanks for you help

[Scott Lanoue]

No problem good luck, if you wanted to you could comment out those dependencies but you’d also need to comment out their usage
