Hello,
I am evaluating Moko-Resources for our kmp project. It works well in android, but I got the following when launching the compose-multiplatform view with an ios-simulator

Can't read color textColor from bundle NSBundle ....bundle> (not yet loaded), please check moko-resources gradle configuration

The module is static due to compose-multiplatform and I have added the Build-Phase for cocoapods-usage…
So what could possibly go wrong? 😉
Do you have any ideas what I am missing?

[alex009]

hi. check please in your ios .app file it contains .bundle with your resources class package

[alex009]

if not contains - check is framework in gradle build directory contains it

[alex009]

if framework not contains - check is you enable gradle plugin in gradle project that have compilation of framework

[alex009]

if framework contains but app not contains - check is you correct setup build phase? maybe this build phase write some errors in log?

[Uli Niggemann]

Hi Aleksey,
the bundle is there. And it looks like all the resources are there, too

[Uli Niggemann]

the runtime-error say (not yet loaded)

[alex009]

hmm

[Uli Niggemann]

more specific *my_lib.bundle> (not yet loaded), please check moko-resources gradle configuration*

[alex009]

all resources on ios at first access load bundle - https://github.com/icerockdev/moko-resources/blob/6bf37f44410e7c4b8316a515810466bd[…]ppleMain/kotlin/dev/icerock/moko/resources/utils/NSBundleExt.kt and then works with this bundle. but i think if you have in multiple bundles same identifier you can confuse this logic

[alex009]

you have multiple bundles or single?

[alex009]

also maybe problem not with bundle. https://developer.apple.com/documentation/uikit/uicolor/2877381-colornamed this error can be if this method return nil . i think it's not related to bundle - we already found bundle but get of color not work

[Uli Niggemann]

there is only one bundle. Do I have to trigger the loading manually if I am using compose-multiplatform?

[alex009]

it's load automatically. error message is invalid - here not only loading bundle issue can be

[alex009]

can you give me color resource config?

[Uli Niggemann]

I just copied the whole https://github.com/icerockdev/moko-resources/tree/6bf37f44410e7c4b8316a515810466bd[…]es/compose-resources-gallery/shared/src/commonMain/resources/MR folder. for testing purpose.

[Uli Niggemann]

string, colors, images are working in android

[Uli Niggemann]

(unfortunately i will be a little more unresponsive from now on, as i have to leave) but thanks a lot for your help!

[alex009]

you compare config of your project with sample?
now i try to configure static framework and check...

[alex009]

here https://github.com/icerockdev/moko-compose-multiplatform-ios-android-template i setup static framework and not see this issue.
can you check please?
if you can reproduce error - create please sample

[Uli Niggemann]

Good morning @alex009. The example is crashing as well…

[Uli Niggemann]

May it be related to my m1Mac?

[alex009]

strange, on my ios simulator it works. i have m1 max

[Uli Niggemann]

same here

[alex009]

describe all test environment please.
ios simulator or device
ios version
xcode version

[Uli Niggemann]

sure, mom

[Uli Niggemann]

xcode Version 14.3 (14E222b)
simulator iPadMini (6th Gen) 16.4
or iPhoneX 16.1.2 (20B110)

[alex009]

i now have xcode 14.1

[alex009]

i test later this simulators with this versions. if not reproduce - i download 14.3

[Uli Niggemann]

wait a minute, i’ll test

[Uli Niggemann]

(i have 14.1 installed as well)

[Uli Niggemann]

Maybe it is just the bundle name? in your case “MyApplication/shared.bundle” - this should be a invalid filename

[alex009]

but on my machine all works)

[alex009]

so it's not just filename problem

[Uli Niggemann]

It also crashes with 14.1…

[alex009]

now i run on 16.1 ios

[Uli Niggemann]

could you please have a look at Bundle.allBundles at runtime?

[Uli Niggemann]

the desired bundle is not listed

[alex009]

send me copy of code please 🙂

[Uli Niggemann]

print(Bundle.allBundles)
will do

[alex009]

loading of bundle is lazy

[alex009]

you try to read bundle list before MR was loaded

[alex009]

print(Bundle.allBundles)
let bundle = MR.images.shared.nsBundle
print(bundle)
print(Bundle.allBundles)

[Uli Niggemann]

ah sorry, you are right

[alex009]

print(Bundle.allBundles)
        let colors = MR.colors.shared
        print(colors.nsBundle)
        print(colors.textColor.bundle)
        print(Bundle.allBundles)
        
        let color = UIColor(
            named: colors.textColor.name,
            in: colors.textColor.bundle,
            compatibleWith: nil
        )
        print("color: \(color)")

[alex009]

try this

[alex009]

i successful got color

[Uli Niggemann]

mom

[alex009]

i think something wrong with compatibleWith parameter...

[Uli Niggemann]

could the kotlin or gradle-version matter?

[alex009]

i think not

[alex009]

also we both test on same code

[alex009]

so problem in enviroment. something different and same code give different results

[alex009]

https://stackoverflow.com/a/74189389/9931244 in native ios same problem resolve by just build cleanup 😄

[alex009]

let color = UIColor(
            named: colors.textColor.name,
            in: colors.textColor.bundle,
            compatibleWith: UITraitCollection.current
        )

check this?

[alex009]

print("traits: \(UITraitCollection.current)")

and this

[Uli Niggemann]

no, still the same

[alex009]

i see

traits: <UITraitCollection: 0x600003e5f500; UserInterfaceIdiom = Phone, DisplayScale = 3, DisplayGamut = P3, HorizontalSizeClass = Compact, VerticalSizeClass = Regular, UserInterfaceStyle = Light, UserInterfaceLayoutDirection = LTR, ForceTouchCapability = Unavailable, PreferredContentSizeCategory = L, AccessibilityContrast = Normal, UserInterfaceLevel = Base>

[Uli Niggemann]

may it be a race-condition?

The bundle is there, but not loaded

[Uli Niggemann]

…yet

[alex009]

in my logs it "not yet loaded" too

[Uli Niggemann]

hm, ok

[Uli Niggemann]

but still: is MyApplication:shared.bundle == MyApplication/shared.bundle

[Uli Niggemann]

your naming is the same, isn’t it?

[alex009]

NSBundle </Users/amikhailov/Library/Developer/CoreSimulator/Devices/5C91DD9B-AE1A-4BB5-A58B-ED2D322D691D/data/Containers/Bundle/Application/3D530DCE-1D31-4BF9-A871-E19E2FD8E856/My application.app/My application:shared.bundle> (not yet loaded)

it's bundle that resources found and there contains color

[alex009]

[Uli Niggemann]

sorry, missed it - mom

[Uli Niggemann]

traits: <UITraitCollection: 0x600001677000; UserInterfaceIdiom = Phone, DisplayScale = 3, DisplayGamut = P3, HorizontalSizeClass = Compact, VerticalSizeClass = Regular, UserInterfaceStyle = Light, UserInterfaceLayoutDirection = LTR, ForceTouchCapability = Unavailable, PreferredContentSizeCategory = L, AccessibilityContrast = Normal, UserInterfaceLevel = Base>

[alex009]

so and traits is same...

[alex009]

let files = colors.textColor.bundle
            .paths(forResourcesOfType: nil, inDirectory: nil)
            .forEach { print($0) }

[alex009]

try this too

[Uli Niggemann]

is your “physical” bundle also called MyApplication/shared.bundle?

[alex009]

[Uli Niggemann]

ah

[Uli Niggemann]

your bundle name is different

[alex009]

hmmmmm

[alex009]

oh, i got crash. after clean of gradle and xcode caches

[alex009]

so for me works old bundled from dynamic framework configurations i think

[Uli Niggemann]

sorry to say, but that’s good 😉

[alex009]

Untitled

Untitled

[alex009]

yes, it's good

[alex009]

so i think we have some diff between bundles for static framework and bundles for dynamic framework oO

[alex009]

in broken bundle Assets not compiled

[alex009]

and same not compiled assets located in gradle cocoapods dir. so it's some gradle plugin problem

[Uli Niggemann]

but this looks good on my side

[alex009]

xcassets - is not compiled version

[alex009]

compiled is car

[Uli Niggemann]

ups 😳

[Uli Niggemann]

so it is something in copyFrameworkResourcesToApp and the bundle could not be loaded because of this?

[alex009]

no. problem in bundle packaging. i already found bug and now prepare for release bugfix

[alex009]

0.22.2 published. please check

[Uli Niggemann]

Yes, it works! ❤️

Thanks a lot!

[alex009]

thanks for help in debugging

[Uli Niggemann]

No, thank you. That’s really great. I think this will save us a lot of time, the idea is great.

[Uli Niggemann]

Now we can face the next big requirement which is multi brand resources 🙈
