Regarding SKIE, I am seeing that my @ShouldRefineInSwift annotations are just causing those fields to disappear in my headers. Is there a way to work around this?

[Filip Dolník]

Hi! I’m not sure I understand the problem correctly. Do you have some example?

[Jacob Rhoda]

Yeah, so I enable SKIE and run it on my project (latest version). I have a class that looks like this,

@OptIn(ExperimentalObjCRefinement::class)
actual abstract class ViewModelContainerHost<STATE: Any, SIDE_EFFECT: Any>
    : ContainerHost<STATE, SIDE_EFFECT> {
    @HiddenFromObjC
    public actual val viewModelScope = CoroutineScope(SupervisorJob() + Dispatchers.Main)

    @ShouldRefineInSwift
    val stateValue
        get() = container.stateValueNative
    @ShouldRefineInSwift
    val stateFlowNative
        get() = container.stateFlowNative
    @ShouldRefineInSwift
    val sideEffectFlow
        get() = container.sideEffectFlowNative
}

I am not yet using SKIE’s Flow translation — incrementally adopting it.

This produces a header that looks like this…

__attribute__((swift_name("ViewModelContainerHost")))
@interface TMSViewModelContainerHost<STATE, SIDE_EFFECT> : TMSBase <TMSContainerHost>
@property (readonly) TMSKotlinUnit *(^(^sideEffectFlow)(TMSKotlinUnit *(^)(SIDE_EFFECT, TMSKotlinUnit *(^)(void), TMSKotlinUnit *), TMSKotlinUnit *(^)(NSError * _Nullable, TMSKotlinUnit *), TMSKotlinUnit *(^)(NSError *, TMSKotlinUnit *)))(void) __attribute__((swift_private));
@property (readonly) TMSKotlinUnit *(^(^stateFlowNative)(TMSKotlinUnit *(^)(STATE, TMSKotlinUnit *(^)(void), TMSKotlinUnit *), TMSKotlinUnit *(^)(NSError * _Nullable, TMSKotlinUnit *), TMSKotlinUnit *(^)(NSError *, TMSKotlinUnit *)))(void) __attribute__((swift_private));
@property (readonly) STATE stateValue __attribute__((swift_private));
- (instancetype)init __attribute__((swift_name("init()"))) __attribute__((objc_designated_initializer));
+ (instancetype)new __attribute__((availability(swift, unavailable, message="use object initializers instead")));
@end

Which is adding the swift_private attribute to those properties. When you try to access them from Swift code, Xcode gives this error:

However, neither the prefix __ nor the non-prefixed name works.

This was working before I adopted SKIE

That looks like a bug in SKIE. I don’t think there is a workaround, but it should be an easy fix on our end. So I think I’ll be able to bundle that into the next release which is scheduled early next week.

Thanks! Need me to open an issue on Github?

[Filip Dolník]

In this case it’s not needed since I’ll fix it right away.
