hi guys, has someone idea about what this error means
```Class 'androidx.compose.runtime.Composable' is compiled by a new Kotlin compiler backend and cannot be loaded by the old compiler```

what is your gradle setup?

This is an indication that you’re trying to compile your code with an older kotlin compiler than what compose runtime got compiled  with. Make sure you’re using kotlin 1.4

I ran the task failing with stacktrace, seems that I forgot to add
```        useIR = true```
lets see if it works

``` useIR = true```
what this means ? <@UEJCGUJCA>

this has the kotlin compiler use the new IR backend that they’ve been working on. compose depends on this backend

`buildFeatures { compose true }` should turn this on though

was this on a non-compose enabled module in your app?

for me ? no it’s in a compose project, but i just wanted to know the meaning of it, thanks.

for me neither,  I have viewBinding enabled but I’m trying to add compose to my project but has been a nightmare haha

ah. yeah, i’m not personally sure how well viewBinding and compose inter-mix. I think some others have tried it out but I have not

<@U5SCRC68Y> Hi I have same problem. I got this issue when try to check state value in break point. did you find any solution? My issue is inside composable functions.
