the function apiResolutionOptions returns a list of Strings

[Muaz KADAN]

are you using xcframework on iOS side ?

[Hristijan]

Yes

[Muaz KADAN]

And you are using compose resources as I can see ?

[Hristijan]

It might be due to this being a navhost too, yes also resources

[Muaz KADAN]

compose resources doesn't get packed with the xcframework

[Muaz KADAN]

that's why the ios code isn't finding them

[Hristijan]

But other destinations that use the resources work, just this one doesn't

[Muaz KADAN]

oh
I had a similar problem because of resources
then I moved to using #CMC5LN42W

[Hristijan]

So I thought maybe string malformed or some characters not supported

[Muaz KADAN]

which solved the resources issue

[Muaz KADAN]

is your code in a public repository ?

[Hristijan]

Nope

https://youtrack.jetbrains.com/issue/KT-66790/Provide-compose-resources-together-with-XCFramework-with-SPM-or-Cocoapods

[Hristijan]

I think it might be one of the problems:

• Kotlinx serialization as NavHost uses that in the background and I'm passing a list of String
• The list has an invalid Swift/ObjC character
• NavHost parsing issue

[Jimmy Jose]

hi @Hristijan Did you happen to figure this out?

[Hristijan]

@Jimmy Jose no and I didn't have time to report the bug, it's probably due to the length of the string on iOS
