Kotlinx.coroutines: Cannot find protocol declaration for SharedCodeKotlinCoroutineContextElement

[NilsLattek]

Kotlin: 1.3.40
Coroutines: 1.2.2
Gradle: 5.4.1

After upgrading Kotlin and coroutines we receive the following error in Xcode for our ios build:

__attribute__((swift_name("KotlinCoroutineContext")))
@protocol SharedCodeKotlinCoroutineContext
@required
- (id _Nullable)foldInitial:(id _Nullable)initial operation:(id _Nullable (^)(id _Nullable, id<SharedCodeKotlinCoroutineContextElement>))operation __attribute__((swift_name("fold(initial:operation:)")));
- (id<SharedCodeKotlinCoroutineContextElement> _Nullable)getKey:(id<SharedCodeKotlinCoroutineContextKey>)key __attribute__((swift_name("get(key:)")));
- (id<SharedCodeKotlinCoroutineContext>)minusKeyKey:(id<SharedCodeKotlinCoroutineContextKey>)key __attribute__((swift_name("minusKey(key:)")));
- (id<SharedCodeKotlinCoroutineContext>)plusContext:(id<SharedCodeKotlinCoroutineContext>)context __attribute__((swift_name("plus(context:)")));
@end;

Cannot find protocol declaration for 'SharedCodeKotlinCoroutineContextElement'; did you mean 'SharedCodeKotlinCoroutineContextKey'?

I have the same issue.

Because there's a circular dependency between KotlinCoroutineContext and KotlinCoroutineContextElement there needs to be a forward declaration of the KotlinCoroutineContextElement at the top of the header file, like:

@protocol SharedCodeKotlinCoroutineContextElement;

I found in my headerfile there were already some similar forward declarations which suggests this is something that's been considered, but for whatever reason is not working in this specific instance.

I found that manually editting the header file could resolve the problem, but this isn't a viable solution.

This is a regression in Kotlin Native 1.3.40.
It's already fixed in upcoming 1.3.41.

Will keep it open until release with 1.3.41.
