Hi, I’m having an issue with casting to shared Kotlin/native classes in Swift when building for release.

I have the following class in the shared module: User.UserGenderProperty.Gender. On the Swift side an object of that class is casted like this:

if let gender = attribute.value as? User.UserGenderPropertyGender { ... }

where attribute is a PropertyOption<User.UserGenderProperty.Gender> and value should be of exactly that type I’m casting to.

When printing out the type of attribute.value I get SharedUserUserGenderPropertyGender which looks to be right.

The generated header file looks fine as well:

__attribute__((objc_subclassing_restricted))
__attribute__((swift_name("User.UserGenderPropertyGender")))
@interface SharedUserUserGenderPropertyGender : SharedKotlinEnum<SharedUserUserGenderPropertyGender *>
+ (instancetype)alloc __attribute__((unavailable));
+ (instancetype)allocWithZone:(struct _NSZone *)zone __attribute__((unavailable));
- (instancetype)initWithName:(NSString *)name ordinal:(int32_t)ordinal __attribute__((swift_name("init(name:ordinal:)"))) __attribute__((objc_designated_initializer)) __attribute__((unavailable));
@property (class, readonly) SharedUserUserGenderPropertyGender *female __attribute__((swift_name("female")));
@property (class, readonly) SharedUserUserGenderPropertyGender *male __attribute__((swift_name("male")));
+ (SharedKotlinArray<SharedUserUserGenderPropertyGender *> *)values __attribute__((swift_name("values()")));
@property (readonly) SharedStringResource *promptInputRes __attribute__((swift_name("promptInputRes")));
@end

But the cast doesn’t succeed in release builds, so apparently SharedUserUserGenderPropertyGender in this build type doesn’t conform to User.UserGenderPropertyGender for whatever reason. In debug builds all is good. 🤷

I’m at a loss here, does someone have an idea what might be wrong?
