No gonna lie, today i was decided to implement Rom in KMP with the documentation provided for google. And Philipp comes with this video, it is truly insane. Philipp you saved my day, tanks a lot!!!

Hi Philipp, Can we use Room for Desktop also ?

@andreaslinis1586 Ай бұрын

I used to have roomdb then wanted to migrate for kotlin multiplatform so changed to sqldelight. Now room is available for kotlin multi platform too. Too late 😂😂😂

For Kotlin 2.0.0, there seems to be an issue syncing 'Cannot change attributes of configuration ':composeApp:debugFrameworkIosX64' after it has been locked for mutation', have used the latest KSP so that IDE identifies generated sources, but still throwing this error. Any one had any luck with this?

@ZAKIALAM 28 күн бұрын

Philips this error is emerged from Kotlin 2.0.0 and KSP 2.0.0. Could you please help ?

I had the same issue. Replace (for now) : dependencies { //room //Replace it with -> ksp(libs.room.compiler) when it is stable add("kspCommonMainMetadata", libs.room.compiler) } tasks.withType().configureEach { if (name != "kspCommonMainKotlinMetadata" ) { dependsOn("kspCommonMainKotlinMetadata") } } I think they will notice and they will come up with a change.

Great video, thanks! By the way, context exists on iOS as well. Core Data, which is the native persistence method in iOS, uses it too. However, for some reason, Kotlin databases on iOS, like Room or SQLDelight, don't seem to require it.

@PhilippLackner Күн бұрын

Interesting, they're still two different contexts though 😄

Philip is it safe to use compose multiplatform for production in this point or is it a bit risky with alpha version? (Jetbrains focus to release beta this year)

Hey Philipp, great video! However, I noticed that you did all of your code in :composeApp. Why did you take this approach and not in the :shared module? I was under the impression that :shared is used for business logic...

@deriarmanda7807 20 күн бұрын

composeApp is a shared module. Right now, they shipped android and kmm together into one module named composeApp by default if you create project from kmp wizard.

@nishantaanjaneyjalan8583 17 күн бұрын

@@deriarmanda7807 Yeah that was quite confusing for me. Now I use `shared/` module for stuff that is shared between the app the server like serializing request/response bodies and type-safe routing.

Hii Philipp.. KSP has generate source code but instantiateImpl() is not resolved in iOS SourceSet. But it is resolved in Android SourceSet. I couldn't figure out the root cause. I have checked generated build folder. I found the method in both iOS & Android generated files but am not getting why it is not resolved in iOS source set resulting in build failure. Please help us to resolve this.

On a physical iOS device (iPhone), I encountered an error when using NSHomeDirectory in the databaseBuilder: Error Domain=KotlinException Code=0 "Unable to open lock file (Operation not permitted)". However, this issue did not occur on the simulator, where it worked fine. To resolve this, I replaced: val dbFile = NSHomeDirectory() + "/myDatabase.db" with val docDirectoryUrl = NSFileManager.defaultManager().URLForDirectory(NSDocumentDirectory, NSUserDomainMask, null, true, null) val dbFile = docDirectoryUrl?.path + "/myDatabase.db" and it worked fine. Does anyone have other suggestions? Thanks.
