I'm trying to set up TimeTravelServer in the iOS project following construction in the documentation but still can not import the TimeTravelServer. Tried to sync gradle and build many times (in android studio and Xcode). Please help!

[Arkadii Ivanov]

Can you show the full build.gradle file?

First of all, something looks wrong here. E.g. you only export mvikotlin-timetravel, but in the Swift code you also use DataStoreKt. It looks like XCode uses another Gradle module, not this one.

Another idea, it could be a bug in Cocoapods plugin. There were multiple occurrences when some dependencies are not visible in Xcode. I recommend switching to Regular Framework if possible (e.g. if you are not using Pod dependencies in Kotlin).

[Arkadii Ivanov]

Oh, is DataStoreKt is defined in the module itself?

[Tung97 Hl]

DataStoreKt is my shared code, it's not count. But let me try your suggestion

[Arkadii Ivanov]

If you could provide a reproducer of this issue, this would be very useful. I really would like to catch this bug in Cocoapods plugin and report it to JetBrains. This is not the first time.

[Arkadii Ivanov]

E.g. you could try stripping all your code, and see if the problem is still there, and then upload to GitHub or drop an archive here.

[Tung97 Hl]

I'll try. Sometimes issues appear and then are gone but I don't know why 😂

[Tung97 Hl]

I solved it by creating expect/actual function to start the time travel server.

[Arkadii Ivanov]

Hmm, interesting! Thanks for sharing!

[Tung97 Hl]

Do you know how to fix this error?

[Tung97 Hl]

run the client in macos by gradle cmd is ok

./gradlew :mvikotlin-timetravel-client:app-desktop:run

but package to dmg then install will go error

[Arkadii Ivanov]

Hmm, thanks for reporting, never seen this error before. Sorry. I will try checking it.

[Arkadii Ivanov]

Btw, you can also use the idea plugin.

[Tung97 Hl]

Thank you

[Arkadii Ivanov]

I couldn't reproduce the issue. Would you be able to provide a full stack trace?

[Arkadii Ivanov]

Also, if you still have that crash, could you please try the following patch and see if it fixes the issue? If it does, I would commit the fix.

Time_Travel_desktop_client_patch.patch

[Tung97 Hl]

I realize I just need restart my computer then this issue is gone. But I can not capture any event even in android or ios. So I just used LoggingStoreFactory to debug.

[Tung97 Hl]

Anyway, let me try the patch then try to use the TimeTravel client again. Currently I'm happy with logging 😊
