Compiling SwiftUi for desktop when using cocoaPods fails

[luca992]

The following error is thrown:

ld: in /<path>/app/build/cocoapods/framework/app.framework/app(combined.o), 
building for UIKitForMac, but linking in object file built for macOS, file 
'//<path>/app/build/cocoapods/framework/app.framework/app' for architecture x86_64

Looks related to this
Libraries coming into the UIKit for Mac environment need to be compiled for the iOS platform, not the macOS platform.

Hello! Thank you for the report.
Can you please provide an additional information on the project?
What was the target you were building for? Is this issue reproducible for some simple project, or you cannot get it outside of the current one?

[luca992]

In the kotlin project I am targeting macosX64, iosX64, iosArm64. I think it should be reproducible with any simple project. I can make one if you would like.

[artdfel]

Okay, I see. If it is possible to have an accurate way to reproduce this, it would be very helpful.

Just open SwiftUi Kotlin Native Test/SwiftUi Kotlin Native Test.xcworkspace

Running on iphone simulator works.
Running on desktop fails with the error I reported

FYI: CocoaPods/CocoaPods#8877 (comment)

So the code needs to be compiled with extra CFLAGS and LDFLAGS. I am yet unsure if this can be done easily in build.gradle for Kotlin Native or Multiplatform, or a bigger change is needed.

Is there anyway to workaround this?
I tried replacing $OTHER_CFLAGS with -target x86_64-apple-ios-macabi -miphoneos-version-min=13.0 in the generated podspec file, and running pod install again. That did not help

This is not supposed to work.

I'm not aware of any.

[luca992]

So does a new target for swiftui desktop need to be created?
similar to this commit adding linux/arm64 support?

This should help, but I'm not sure that this is the only option.
