Is it possible to refer to resource file that is i...

# ios

[Konstantin Petrukhnov]

Is it possible to refer to resource file that is inside ".framework" bundle, from arm64/x64 source? E.g. mpp library project, that have sources and few resource files. In jvm files inside jar could be access through classpath, but is it possible to do similar on ios? Now I'm using Bundle.url(forResource) in swift, and then pass path string to kotlin, that will access file.

Why not use the same from Kotlin?

See e.g. https://github.com/Kotlin/kotlinconf-spinner/blob/a961d250954cdceefd1ecf29261ffbd67e1161e0/common/src/iosMain/kotlin/kommon/Kommon.kt

in case of .framework you just should use not Bundle.main but NSBundle.bundleForClass(object_getClass(this)!!) (with class from framework)
like in plugin https://github.com/icerockdev/moko-resources/blob/327eef878d929ec78cc38eb7202b99404a400874/gradle-plugin/src/main/kotlin/dev/icerock/gradle/generator/IosMRGenerator.kt#L46

[Konstantin Petrukhnov]

Thx. Both examples are very useful!

[Konstantin Petrukhnov]

Hm.. still can't get it working. Tried both, but pathForResource(,,) always return null.
NSBundle.mainBundle.bundlePath and NSBundle.bundleForClass(object_getClass(this)!!).bundlePath return some string with ".app"

[Konstantin Petrukhnov]

I think I should specify somehow bundle... but inside the library I don't know framework name....

[Konstantin Petrukhnov]

e.g. in ios code I was using something like this: Bundle(url: Bundle.main.bundleURL.appendingPathComponent("MyKotlin.bundle"))!

[Konstantin Petrukhnov]

but MyKotlin project have dependency on libA, that actually have code tthat should load resource

[Konstantin Petrukhnov]

any thoughts? @svyatoslav.scherbina @alex009

[alex009]

in NSBundle.bundleForClass(object_getClass(this)!!) you should give class from framework, not from app

[Konstantin Petrukhnov]

NSBundle.bundleForClass(object_getClass(BundlePathResolver())!!).bundlePath return same path as mainBundle

[Konstantin Petrukhnov]

So I have MyApp, that use MyFramework, that use MyLib. file.txt is inside MyFramework.framework (cocoapods). In MyLib, I'm trying to load that file. In that lib I can't give class from MyFramework, as lib could be used in multiple frameworks.

[Konstantin Petrukhnov]

@alex009 in swift code in ios, Bundle(for: NSClassFromString("KotlinInt")!) refer to main bundle and not to kotlin .framework

[alex009]

strange. we use it in our projects (in moko-resources)

[svyatoslav.scherbina]

@Konstantin Petrukhnov I guess your framework is static. In this case you can’t get path to the framework bundle with NSBundle.bundleForClass, as all code including classes is linked into main application binary. And this is not Kotlin-specific.

[Konstantin Petrukhnov]

@svyatoslav.scherbina how do i produce dynamic one? Any example?

[svyatoslav.scherbina]

Try configuring your framework with isStatic = false.
You may then require enabling use_frameworks in your application Podfile.

[Konstantin Petrukhnov]

@svyatoslav.scherbina It seems that isStatic and export don't work together very well. Example:
https://github.com/Ekahau/khtf-iosapp-fw/blob/master/build.gradle
If 'isStatic = false' uncommented, then other libs are not exported to framework.

[svyatoslav.scherbina]

This shouldn’t be related at all. Could you recheck with clean build?

[svyatoslav.scherbina]

How does it reproduce anything related to your report above:

If ‘isStatic = false’ uncommented, then other libs are not exported to framework.

?
I can’t find an export in your build script.

Considering isStatic having no effect: your build script doesn’t seem correct. Replacing binaries.findAll { ... }.every { with binaries.matching { ... }.all { makes it.isStatic = false work as expected.

[Konstantin Petrukhnov]

With suggested change, it works. Thank you very much!
