Unfortunately
HttpsCallableReference
does not use internal reference counting, and as a result, we need to avoid the copy-constructor forHttpsCallableReference
. Otherwise, if Swift creates a copy of the object and deletes that copy, it will result in any pendingCall
being interrupted or triggering memory corruption in the case thatCall
has not completed. To avoid this and to prevent Swift from seeing the copy constructor, wrap with astd::shared_ptr
.
