Having this

sealed class

?

sealed class ResultWrapper<T> {
data class Success<T>(val data: T) : ResultWrapper<T>()
data class Unauthorized(val exception: UnauthorizedException) : ResultWrapper<Nothing>()
data class Forbidden(val exception: ForbiddenException) : ResultWrapper<Nothing>()
data class Network(val exception: NetworkException) : ResultWrapper<Nothing>()
data class NotFound(val exception: NotFoundException) : ResultWrapper<Nothing>()
data class BadRequest(val exception: BadRequestException) : ResultWrapper<Nothing>()
data class Error(val exception: Exception) : ResultWrapper<Nothing>()
}

Then I have a method that returns a

ResultWrapper<T>

but I'm only able to return the

ResultWrapper.Success(it)

how can I return the other ones?

What happens when you try to return the other ones?

I solved it adding a <T> in front and changing the <Nothing> by <T>.

I think

sealed class ResultWrapper<out T>

should have worked fine too.

True that.
