Kotlin Multiplatform Mobile unable to run on iOS: Execution failed for task ':shared:compileKotlinIosX64'

Question

I have created fresh project(Hello World) in KMM followed by their official website. In android it works smooth but when I am trying to run in XCode it's giving errors because of which I am unable to build / run the xcode project. I have attached screenshots and logs for my errors. Somehow xcode scheme is not getting generated in the KMM platform that's what I am guessing. Can anyone please help me understand what am I missing? Any help would be appriciated.

Following is my dev env:

Xcode 11.4.1
Android 4.1.2
Kotling Plugin version 1.4.30 (stable)
KMM 0.2.0```


XCode Logs:

Can you share the project? It might be that some of your dependencies don't have an iosX64 target or your actual implementations are not working for this target – Nikitanikki

@NagyRobi nothing fancy added yet but still. Here is the github link which you can go through. github.com/fatinWasta/kmm_demo – Begird

@FatinWasta I just compiled your app in A.S - 4.1.2 and it works fine for both android and iOS – Zacharie

Which version are you using for android and for xcode ? – Zacharie

Also can you please check if you have set Command Line Tools in your Xcode ? You can check from :- Xcode -> Preferences -> Locations -> Command Line tools. – Zacharie

@MohammedHanif. Following is my dev env: Xcode 11.4.1 cmd lines tools are 11.4.1 Android 4.1.2 Kotling Plugin version 1.4.30 (stable) KMM 0.2.0``` – Begird

maybe this can help looks similar to me :- #64031101 – Zacharie

@MohammedHanif. above link is when there are two xcodes and cmd line tool couldnt decide about which to follow. I have only one. Can you please let me know your system env? – Begird

@FatinWasta Xcode version - 12.0.1 same for cmd tools all others are same as yours. – Zacharie

did that help you ? – Zacharie

@MohammedHanif. no it didn't. :( – Begird

does running same project from Xcode itself works or not ? – Zacharie

@MohammedHanif. nope it doesn't. I have added the screenshots what happens if I run it from XCode. – Begird

Does this answer your question? How to configure an iOS Application for Kotlin Multiplatform in Android Studio? – Sailor

If this does not work even after following the solution on youtrack, anyone can try this answer – Salvatore

@FatinWasta did u find a solution? – Necktie

the same. Did anyone find a solution? – Necktie

Hey Guys, mods deleted my answere where I shared the details. This issue happened to me cause of corrupted kotlin files, you can try reinstalling kotlin. Also try checking your cmd line tools in XCode as per comments. Here is ticket which I created on jetbrains for support. youtrack.jetbrains.com/issue/KT-44805 – Begird

Solution: Deleted clang-llvm-apple-8.0.0-darwin-macos, Clean gradle Rebuild in Xcode. auto initiated download in /Users/fatin/.konan/cache/clang-llvm-apple-8.0.0-darwin-macos (^ Took almost 5hrs to download, can be cause of my connection but not sure cause everything else loads well.) As soon as file is downloaded succesively, XCode build succeeded. Now I can run in iOS sim via XCode. – Begird

Answer 1

May be your project kotlin version is not matching with cached version. Try following techniques

1. Delete the .konan directory from your home directory, it was hidden in mac.
2. Check jdk version in the system and match it with your java version in project.
3. Delete all the generated folders from project root, invalidate and restart the Android Studio.

Answer 2

If the project doesn't run right away even on opening it from Xcode and shows the shared framework is missing, Then try generating the shared framework for iOS platform using terminal. Navigate to the project folder and execute Command: ./gradlew packForXcode Now the shared framework should have a xcode-frameworks product and you should be able to build and run the project through Xcode.

Answer 3

This could happen if there are two libraries, where one library was compiled against the different version of the other library than the one currently used in the project. Please check that the project configuration is correct and has consistent versions of dependencies.
