Hi there, I'm trying to run 
moko-socket-io
project I'm able to run the sample android app after changing target sdk, jdk and installing pod dependencies but the ios sample app build is failing with following outputs. I'm trying to implement changes for this issue. Please help me setup iOS project. Thanks in advance! 1. 
./gradlew build publishToMavenLocal syncMultiPlatformLibraryDebugFrameworkIosX64

here you not show error. this warning not related to FAILED state. please give more log. i think you just not do 
pod install
before run 
./gradlew build publishToMavenLocal syncMultiPlatformLibraryDebugFrameworkIosX64
and cinterop can't find native lib. next step issue just same - you should show full log with error, not just "task failed"

Sorry for late reply I'd executed pod install before running the gradle task and this was the output:

here's the full log for the gradle task: https://scans.gradle.com/s/5xdp7aj76ikvy Let me know you need anything else. Thanks!
I've updated agp, kotlin version in my fork and tried running the same gradle task and xcode command, both gradle task and xcodebuild command are executing successfully (both on local and ci/cd job) here's the gradle task scan log. output of xcodebuild command:

but if I run the sample ios app from xcode/androidstudio the build is throwing error so not able to see any output on simulator :

I'm not sure if any issue with my env/sdk versions.

in gradle scan you can see:
Copy code
The /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld command returned non-zero exit code: 1.	
output:	
-iphoneos_version_min has been renamed to -ios_version_min	
ld: unknown options: -sdk_version
thats mean that you use xcode version newest than supported by kotlin gradle plugin in project. need to update kotlin gradle plugin
you already update in your fork as i see, its good. error:
Copy code
ld: warning: ignoring file '/Users/whoknows/Developement/OSS/moko-socket-io/sample/mpp-library/build/cocoapods/framework/MultiPlatformLibrary.framework/MultiPlatformLibrary': found architecture 'x86_64', required architecture 'arm64'
ld: Undefined symbols:

mean that 
MultiPlatformLibrary
compiled for x86_64 but you now build ios app for arm64 architecture. i think you try to run on iOS simulator on m1 mac. need to update kotlin targets list and cocoapods integration
add please in gradle.properties this one option:
Copy code
mobile.multiplatform.withoutIosSimulatorArm64=false
and also update podspec file to:
Copy code

Thanks for replying. I updated these and tried to run it (pod install and same steps) still getting error on AS/XCode run, gradle task and xcodebuild command is not an issue but getting error on AS/XCode run, here's the log file:

this mean that pods was not found/not compiled. check that you run 
pod install
before gradle compilation. gradle should see pods and successfully compile them to link with binaries
a
pod install gave this output:
Copy code
Analyzing dependencies
Downloading dependencies
Generating Pods project
Integrating client project
Pod installation complete! There are 2 dependencies from the Podfile and 4 total pods installed.
should I run after pod install?
Copy code
./gradlew build publishToMavenLocal syncMultiPlatformLibraryDebugFrameworkIosArm64
or
Copy code
./gradlew build publishToMavenLocal syncMultiPlatformLibraryDebugFrameworkIosX64
a
Copy code
./gradlew build publishToMavenLocal syncMultiPlatformLibraryDebugFrameworkIosSimulatorArm64
this one will be better. is this command run successful?
a
no this is giving task not found error:
Copy code
FAILURE: Build failed with an exception.

* What went wrong:
Task 'syncMultiPlatformLibraryDebugFrameworkIosSimulatorArm64' not found in root project 'moko-socket-io' and its subprojects.
also tried with those 2 it gives same error on simulator run
a
a
Yes, after this change I re run the pod install command then the gradle task
@alex009 I was not able to fix this, is there any other way I should try? You can point me to some resources where I can learn more about these things?
a
hi. please push all current changes to your fork and give me link to actual branch, i will check it on this weekend
a
thanks @alex009, this (dev) is the branch were all these changes are pushed, Let me know anything else you need.
a
a
Thanks a lot! I'll merge and try to run it
Finally 🎉
